 1345 \`configure' configures GNU Awk 5.1.0 to adapt to many kinds of systems.
 1346 
 1347 Usage: $0 [OPTION]... [VAR=VALUE]...
 1348 
 1349 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 1350 VAR=VALUE.  See below for descriptions of some of the useful variables.
 1351 
 1352 Defaults for the options are specified in brackets.
 1353 
 1354 Configuration:
 1355   -h, --help              display this help and exit
 1356       --help=short        display options specific to this package
 1357       --help=recursive    display the short help of all the included packages
 1358   -V, --version           display version information and exit
 1359   -q, --quiet, --silent   do not print \`checking ...' messages
 1360       --cache-file=FILE   cache test results in FILE [disabled]
 1361   -C, --config-cache      alias for \`--cache-file=config.cache'
 1362   -n, --no-create         do not create output files
 1363       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
 1364 
 1365 Installation directories:
 1366   --prefix=PREFIX         install architecture-independent files in PREFIX
 1367                           [$ac_default_prefix]
 1368   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 1369                           [PREFIX]
 1370 
 1371 By default, \`make install' will install all the files in
 1372 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1373 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1374 for instance \`--prefix=\$HOME'.
 1375 
 1376 For better control, use the options below.
 1377 
 1378 Fine tuning of the installation directories:
 1379   --bindir=DIR            user executables [EPREFIX/bin]
 1380   --sbindir=DIR           system admin executables [EPREFIX/sbin]

 1387   --includedir=DIR        C header files [PREFIX/include]
 1388   --oldincludedir=DIR     C header files for non-gcc [/usr/include]

 1453 
 1454 Some influential environment variables:
 1455   CC          C compiler command
 1456   CFLAGS      C compiler flags
 1457   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 1458               nonstandard directory <lib dir>
 1459   LIBS        libraries to pass to the linker, e.g. -l<library>
 1460   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
 1461               you have headers in a nonstandard directory <include dir>
 1462   CPP         C preprocessor
 1463   YACC        The `Yet Another Compiler Compiler' implementation to use.
 1464               Defaults to the first program found out of: `bison -y', `byacc',
 1465               `yacc'.
 1466   YFLAGS      The list of arguments that will be passed by default to $YACC.
 1467               This script will default YFLAGS to the empty string to avoid a
 1468               default value of `-d' given by some make applications.
 1469 
 1470 Use these variables to override the choices made by `configure' or to help
 1471 it to find libraries and programs with nonstandard names/locations.

 3191 Oops!
 3192 
 3193 Your 'rm' program seems unable to run without file operands specified
 3194 on the command line, even when the '-f' option is present.  This is contrary
 3195 to the behaviour of most rm programs out there, and not conforming with
 3196 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
 3197 
 3198 Please tell bug-automake@gnu.org about your system, including the value
 3199 of your $PATH and any error possibly output before this message.  This
 3200 can help us improve future automake versions.
