 1334                           [$ac_default_prefix]

 1336                           [PREFIX]
 1337 
 1338 By default, \`make install' will install all the files in
 1339 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1340 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1341 for instance \`--prefix=\$HOME'.

 1409   CFLAGS      C compiler flags
 1410   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 1411               nonstandard directory <lib dir>
 1412   LIBS        libraries to pass to the linker, e.g. -l<library>
 1413   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
 1414               you have headers in a nonstandard directory <include dir>
 1415   PKG_CONFIG  path to pkg-config utility
 1416   PKG_CONFIG_PATH
 1417               directories to add to pkg-config's search path
 1418   PKG_CONFIG_LIBDIR
 1419               path overriding pkg-config's built-in search path
 1420   CHECK_CFLAGS
 1421               C compiler flags for CHECK, overriding pkg-config
 1422   CHECK_LIBS  linker flags for CHECK, overriding pkg-config
 1423   CPP         C preprocessor
 1424 
 1425 Use these variables to override the choices made by `configure' or to help
 1426 it to find libraries and programs with nonstandard names/locations.

 3015 Your 'rm' program seems unable to run without file operands specified

 3017 to the behaviour of most rm programs out there, and not conforming with
 3018 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
