 1325                           [PREFIX]
 1326 
 1327 By default, \`make install' will install all the files in
 1328 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1329 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1330 for instance \`--prefix=\$HOME'.

 1401 
 1402 Some influential environment variables:
 1403   CC          C compiler command
 1404   CFLAGS      C compiler flags
 1405   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 1406               nonstandard directory <lib dir>
 1407   LIBS        libraries to pass to the linker, e.g. -l<library>
 1408   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
 1409               you have headers in a nonstandard directory <include dir>
 1410   CPP         C preprocessor
 1411 
 1412 Use these variables to override the choices made by `configure' or to help
 1413 it to find libraries and programs with nonstandard names/locations.

 2815 Oops!
 2816 
 2817 Your 'rm' program seems unable to run without file operands specified
 2818 on the command line, even when the '-f' option is present.  This is contrary
 2819 to the behaviour of most rm programs out there, and not conforming with
 2820 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
 2821 
 2822 Please tell bug-automake@gnu.org about your system, including the value
 2823 of your $PATH and any error possibly output before this message.  This
 2824 can help us improve future automake versions.
