 1534 \`configure' configures Hydra 3.3.2 to adapt to many kinds of systems.
 1535 
 1536 Usage: $0 [OPTION]... [VAR=VALUE]...
 1537 
 1538 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 1539 VAR=VALUE.  See below for descriptions of some of the useful variables.
 1540 
 1541 Defaults for the options are specified in brackets.
 1542 
 1543 Configuration:
 1544   -h, --help              display this help and exit
 1545       --help=short        display options specific to this package
 1546       --help=recursive    display the short help of all the included packages
 1547   -V, --version           display version information and exit
 1548   -q, --quiet, --silent   do not print \`checking ...' messages
 1549       --cache-file=FILE   cache test results in FILE [disabled]
 1550   -C, --config-cache      alias for \`--cache-file=config.cache'
 1551   -n, --no-create         do not create output files
 1552       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
 1553 
 1554 Installation directories:
 1555   --prefix=PREFIX         install architecture-independent files in PREFIX
 1556                           [$ac_default_prefix]
 1557   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 1558                           [PREFIX]
 1559 
 1560 By default, \`make install' will install all the files in
 1561 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1562 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1563 for instance \`--prefix=\$HOME'.
 1564 
 1565 For better control, use the options below.

 4984 
 4985 Your 'rm' program seems unable to run without file operands specified
 4986 on the command line, even when the '-f' option is present.  This is contrary
 4987 to the behaviour of most rm programs out there, and not conforming with
 4988 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
 4989 
 4990 Please tell bug-automake@gnu.org about your system, including the value
 4991 of your $PATH and any error possibly output before this message.  This

 5254     # These were added to improve portability
 5255     #   -Wstack-usage=262144 -- 32 bit FreeBSD did not like the mprobe test
 5256     #       allocating a big variable on the stack. (See tt#2160).  The "right"
 5257     #       value requires further investigation; 1 MiB would have at least
 5258     #       caught #2160 at compile-time, and only two other tests show a
 5259     #       warning at 256k.
 5260     #
 5261     # These were added to reduce warnings:
 5262     #   -Wno-missing-field-initializers  -- We want to allow a struct to be
 5263     #       initialized to zero using "struct x y = {0};" and not require
 5264     #       each field to be initialized individually.
 5265     #   -Wno-unused-parameter -- For portability, some parameters go unused
 5266     #       when we have different implementations of functions for
 5267     #       different platforms
 5268     #   -Wno-unused-label -- We add fn_exit: and fn_fail: on all functions,
 5269     #       but fn_fail may not be used if the function doesn't return an
 5270     #       error.
 5271     #   -Wno-sign-compare -- read() and write() return bytes read/written
 5272     #       as a signed value, but we often compare this to size_t (or
 5273     #       msg_sz_t) variables.
 5274     #   -Wno-format-zero-length -- this warning is irritating and useless, since
 5275     #                              a zero-length format string is very well defined
 5276     # These were removed to reduce warnings:
 5277     #   -Wcast-qual -- Sometimes we need to cast "volatile char*" to
 5278     #       "char*", e.g., for memcpy.
 5279     #   -Wpadded -- We catch struct padding with asserts when we need to
 5280     #   -Wredundant-decls -- Having redundant declarations is benign and the
 5281     #       code already has some.
 5282     #   -Waggregate-return -- This seems to be a performance-related warning
 5283     #       aggregate return values are legal in ANSI C, but they may be returned
 5284     #       in memory rather than through a register.  We do use aggregate return
 5285     #       values, but they are structs of a single basic type (used to enforce
 5286     #       type checking for relative vs. absolute ptrs), and with optimization
 5287     #       the aggregate value is converted to a scalar.
 5288     #   -Wdeclaration-after-statement -- This is a C89
 5289     #       requirement. When compiling with C99, this should be
 5290     #       disabled.
 5291     #   -Wfloat-equal -- There are places in hwloc that set a float var to 0, then
 5292     #       compare it to 0 later to see if it was updated.  Also when using strtod()
 5293     #       one needs to compare the return value with 0 to see whether a conversion
 5294     #       was performed.
 5295     #   -Werror-implicit-function-declaration -- implicit function declarations
 5296     #       should never be tolerated.  This also ensures that we get quick
 5297     #       compilation failures rather than later link failures that usually
 5298     #       come from a function name typo.
 5299     #   -Wcast-align -- Casting alignment warnings.  This is an
 5300     #       important check, but is temporarily disabled, since it is
 5301     #       throwing too many (correct) warnings currently, causing us
 5302     #       to miss other warnings.
 5303     #   -Wshorten-64-to-32 -- Bad type-casting warnings.  This is an
 5304     #       important check, but is temporarily disabled, since it is
 5305     #       throwing too many (correct) warnings currently, causing us
 5306     #       to miss other warnings.
 5307     #
 5308     # This was removed because it masks important failures (see ticket #2094).
 5309     # However, since Intel compiler currently does not include -Wtype-limits
 5310     # in -Wextra, -Wtype-limits was added to handle warnings with the Intel
 5311     # compiler.
 5312     #   -Wno-type-limits -- There are places where we compare an unsigned to
 5313     #       a constant that happens to be zero e.g., if x is unsigned and
 5314     #       MIN_VAL is zero, we'd like to do "MPIR_Assert(x >= MIN_VAL);".
 5315     #       Note this option is not supported by gcc 4.2.  This needs to be added
 5316     #       after most other warning flags, so that we catch a gcc bug on 32-bit
 5317     #       that doesn't give a warning that this is unsupported, unless another
 5318     #       warning is triggered, and then if gives an error.
 5319     # the embedded newlines in this string are safe because we evaluate each
 5320     # argument in the for-loop below and append them to the CFLAGS with a space
