   2373 \`configure' configures GNU Bison 2.7 to adapt to many kinds of systems.
   2374 
   2375 Usage: $0 [OPTION]... [VAR=VALUE]...
   2376 
   2377 To assign environment variables (e.g., CC, CFLAGS...), specify them as
   2378 VAR=VALUE.  See below for descriptions of some of the useful variables.
   2379 
   2380 Defaults for the options are specified in brackets.
   2381 
   2382 Configuration:
   2383   -h, --help              display this help and exit
   2384       --help=short        display options specific to this package
   2385       --help=recursive    display the short help of all the included packages
   2386   -V, --version           display version information and exit
   2387   -q, --quiet, --silent   do not print \`checking ...' messages
   2388       --cache-file=FILE   cache test results in FILE [disabled]
   2389   -C, --config-cache      alias for \`--cache-file=config.cache'
   2390   -n, --no-create         do not create output files
   2391       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
   2392 
   2393 Installation directories:
   2394   --prefix=PREFIX         install architecture-independent files in PREFIX
   2395                           [$ac_default_prefix]
   2396   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
   2397                           [PREFIX]
   2398 
   2399 By default, \`make install' will install all the files in
   2400 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
   2401 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
   2402 for instance \`--prefix=\$HOME'.
   2403 
   2404 For better control, use the options below.
   2405 
   2406 Fine tuning of the installation directories:
   2407   --bindir=DIR            user executables [EPREFIX/bin]
   2408   --sbindir=DIR           system admin executables [EPREFIX/sbin]

   2480 Some influential environment variables:
   2481   CC          C compiler command
   2482   CFLAGS      C compiler flags
   2483   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
   2484               nonstandard directory <lib dir>
   2485   LIBS        libraries to pass to the linker, e.g. -l<library>
   2486   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
   2487               you have headers in a nonstandard directory <include dir>
   2488   CXX         C++ compiler command
   2489   CXXFLAGS    C++ compiler flags
   2490   CPP         C preprocessor
   2491   YACC        The `Yet Another Compiler Compiler' implementation to use.
   2492               Defaults to the first program found out of: `bison -y', `byacc',
   2493               `yacc'.
   2494   YFLAGS      The list of arguments that will be passed by default to $YACC.
   2495               This script will default YFLAGS to the empty string to avoid a
   2496               default value of `-d' given by some make applications.
   2497   M4          Location of GNU M4 1.4.6 or later. Defaults to the first program
   2498               of 'm4', 'gm4', or 'gnum4' on PATH that meets Autoconf needs.
   2499 
   2500 Use these variables to override the choices made by `configure' or to help
   2501 it to find libraries and programs with nonstandard names/locations.
