1330 \`configure' configures gdbsupport 1.0 to adapt to many kinds of systems.
1331
1332 Usage: $0 [OPTION]... [VAR=VALUE]...
1333
1334 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1335 VAR=VALUE.  See below for descriptions of some of the useful variables.
1336
1337 Defaults for the options are specified in brackets.
1338
1339 Configuration:
1340   -h, --help              display this help and exit
1341       --help=short        display options specific to this package
1342       --help=recursive    display the short help of all the included packages
1343   -V, --version           display version information and exit
1344   -q, --quiet, --silent   do not print \`checking ...' messages
1345       --cache-file=FILE   cache test results in FILE [disabled]
1346   -C, --config-cache      alias for \`--cache-file=config.cache'
1347   -n, --no-create         do not create output files
1348       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1349
1350 Installation directories:
1351   --prefix=PREFIX         install architecture-independent files in PREFIX
1352                           [$ac_default_prefix]
1353   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1354                           [PREFIX]
1355
1356 By default, \`make install' will install all the files in
1357 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1358 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1359 for instance \`--prefix=\$HOME'.
1360
1361 For better control, use the options below.

1437 Some influential environment variables:
1438   CC          C compiler command
1439   CFLAGS      C compiler flags
1440   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1441               nonstandard directory <lib dir>
1442   LIBS        libraries to pass to the linker, e.g. -l<library>
1443   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1444               you have headers in a nonstandard directory <include dir>
1445   CXX         C++ compiler command
1446   CXXFLAGS    C++ compiler flags
1447   CPP         C preprocessor
1448
1449 Use these variables to override the choices made by `configure' or to help
1450 it to find libraries and programs with nonstandard names/locations.

8443    Here is a matrix of mmap possibilities:
8444         mmap private not fixed
8445         mmap private fixed at somewhere currently unmapped
8446         mmap private fixed at somewhere already mapped
8447         mmap shared not fixed
8448         mmap shared fixed at somewhere currently unmapped
8449         mmap shared fixed at somewhere already mapped
8450    For private mappings, we should verify that changes cannot be read()
8451    back from the file, nor mmap's back from the file at a different
8452    address.  (There have been systems where private was not correctly
8453    implemented like the infamous i386 svr4.0, and systems where the
8454    VM page cache was not coherent with the file system buffer cache
8455    like early versions of FreeBSD and possibly contemporary NetBSD.)
8456    For shared mappings, we should conversely verify that changes get
8457    propagated back to all the places they're supposed to be.
8458
8459    Grep wants private fixed already mapped.
8460    The main things grep needs to know about mmap are:
8461    * does it exist and is it safe to write into the mmap'd area
8462    * how to use it (BSD variants)  */
