[patches] PATCH: Implement the OPTION_EGLIBC_SPAWN option group

[Jim Blandy <jimb@xxxxxxxxxxxxxxxx>]

I've committed the following.

ChangeLog.eglibc:
2007-08-17  Jim Blandy  <jimb@xxxxxxxxxxxxxxxx>

	Implement the OPTION_EGLIBC_SPAWN option group.

	* option-groups.def (OPTION_EGLIBC_SPAWN): New entry.
	* option-groups.defaults (OPTION_EGLIBC_SPAWN): Initialize.
	* posix/Makefile (routines): Move spawn routines into group.
	(tests): Move tst-spawn into group.
	* iconv/Makefile (CPPFLAGS-charmap-dir.c): Pass NO_UNCOMPRESS if
	spawn is not available.
	* locale/Makefile (CFLAGS-charmap-dir.c): Same.
	* nptl/Makefile (tst-exec1): Put in group.

+   help
+      This option group includes the POSIX functions for executing
+      programs in child processes without using 'fork' or 'vfork'.
+
+      This option group includes the following functions:
+
+        posix_spawn
+        posix_spawnattr_destroy
+        posix_spawnattr_getflags
+        posix_spawnattr_getpgroup
+        posix_spawnattr_getschedparam
+        posix_spawnattr_getschedpolicy
+        posix_spawnattr_getsigdefault
+        posix_spawnattr_getsigmask
+        posix_spawnattr_init
+        posix_spawnattr_setflags
+        posix_spawnattr_setpgroup
+        posix_spawnattr_setschedparam
+        posix_spawnattr_setschedpolicy
+        posix_spawnattr_setsigdefault
+        posix_spawnattr_setsigmask
+        posix_spawn_file_actions_addclose
+        posix_spawn_file_actions_adddup2
+        posix_spawn_file_actions_addopen
+        posix_spawn_file_actions_destroy
+        posix_spawn_file_actions_init
+        posix_spawnp
+
+      This option group also provides the ability for the iconv,
+      localedef, and locale programs to operate transparently on
+      compressed charset definitions.  When this option group is
+      disabled, those programs will only operate on uncompressed
+      charmap files.
+
 config OPTION_EGLIBC_SUNRPC
    bool "Support for the Sun 'RPC' protocol."
