\`configure' configures this package to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

  --bindir=DIR            user executables [EPREFIX/bin]

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  CXX         C++ compiler command
  CXXFLAGS    C++ compiler flags
  CXXCPP      C++ preprocessor
  CPP         C preprocessor
  GMPLIBS     How to link GMP
  GMPINC      How to find GMP include files
  ISLLIBS     How to link isl
  ISLINC      How to find isl include files

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

Report bugs to the package provider.

# Assembler & linker features
# ---------------------------

# During stage 2, ld is actually gcc/collect-ld, which is a small script to
# discern between when to use prev-ld/ld-new and when to use ld/ld-new.
# However when ld-new is first executed from the build tree, libtool will
# relink it as .libs/lt-ld-new, so that it can give it an RPATH that refers
# to the build tree.  While doing this we need to use the previous-stage
# linker, or we have an infinite loop.  The presence of a shell script as
# ld/ld-new, and the fact that the script *uses ld itself*, is what confuses
# the gcc/collect-ld script.  So we need to know how libtool works, or
# exec-tool will fail.
