1356 \`configure' configures gdbsupport 1.0 to adapt to many kinds of systems.
1357
1358 Usage: $0 [OPTION]... [VAR=VALUE]...
1359
1360 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1361 VAR=VALUE.  See below for descriptions of some of the useful variables.
1362
1363 Defaults for the options are specified in brackets.
1364
1365 Configuration:
1366   -h, --help              display this help and exit
1367       --help=short        display options specific to this package
1368       --help=recursive    display the short help of all the included packages
1369   -V, --version           display version information and exit
1370   -q, --quiet, --silent   do not print \`checking ...' messages
1371       --cache-file=FILE   cache test results in FILE [disabled]
1372   -C, --config-cache      alias for \`--cache-file=config.cache'
1373   -n, --no-create         do not create output files
1374       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1375
1376 Installation directories:
1377   --prefix=PREFIX         install architecture-independent files in PREFIX
1378                           [$ac_default_prefix]
1379   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1380                           [PREFIX]
1381
1382 By default, \`make install' will install all the files in
1383 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1384 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1385 for instance \`--prefix=\$HOME'.
1386
1387 For better control, use the options below.
1388
1389 Fine tuning of the installation directories:
1390   --bindir=DIR            user executables [EPREFIX/bin]
1391   --sbindir=DIR           system admin executables [EPREFIX/sbin]
1392   --libexecdir=DIR        program executables [EPREFIX/libexec]
1393   --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
1394   --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]

1477 Some influential environment variables:
1478   CC          C compiler command
1479   CFLAGS      C compiler flags
1480   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1481               nonstandard directory <lib dir>
1482   LIBS        libraries to pass to the linker, e.g. -l<library>
1483   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1484               you have headers in a nonstandard directory <include dir>
1485   CXX         C++ compiler command
1486   CXXFLAGS    C++ compiler flags
1487   CPP         C preprocessor
1488
1489 Use these variables to override the choices made by `configure' or to help
1490 it to find libraries and programs with nonstandard names/locations.

3534 You can download and install GNU coreutils to get an 'rm' implementation
3535 that behaves properly: <http://www.gnu.org/software/coreutils/>.
3536
3537 If you want to complete the configuration process using your problematic
3538 'rm' anyway, export the environment variable ACCEPT_INFERIOR_RM_PROGRAM
3539 to "yes", and re-run configure.

11110    Here is a matrix of mmap possibilities:
11111         mmap private not fixed
11112         mmap private fixed at somewhere currently unmapped
11113         mmap private fixed at somewhere already mapped
11114         mmap shared not fixed
11115         mmap shared fixed at somewhere currently unmapped
11116         mmap shared fixed at somewhere already mapped
11117    For private mappings, we should verify that changes cannot be read()
11118    back from the file, nor mmap's back from the file at a different
11119    address.  (There have been systems where private was not correctly
11120    implemented like the infamous i386 svr4.0, and systems where the
11121    VM page cache was not coherent with the file system buffer cache
11122    like early versions of FreeBSD and possibly contemporary NetBSD.)
11123    For shared mappings, we should conversely verify that changes get
11124    propagated back to all the places they're supposed to be.
11125
11126    Grep wants private fixed already mapped.
11127    The main things grep needs to know about mmap are:
11128    * does it exist and is it safe to write into the mmap'd area
11129    * how to use it (BSD variants)  */
