Subject: [PATCH] sunrpc: fix rpc bootstrap builds
If you build & install glibc w/rpc disabled, you no longer have headers in
/usr/include/rpc/ (this is expected). But if you try to build glibc w/rpc
enabled, this gets into a bad state due to the new rpc helpers that get
cross-compiled:
$ make
...
x86_64-pc-linux-gnu-gcc -m32 -D_RPC_THREAD_SAFE_ -D_GNU_SOURCE -DIS_IN_build \
-include $objdir/config.h rpc_clntout.c -o $objdir/sunrpc/cross-rpc_clntout.o \
-MMD -MP -MF $objdir/sunrpc/cross-rpc_clntout.o.dt -MT $objdir/sunrpc/cross-rpc_clntout.o -c
rpc_clntout.c:34:23: fatal error: rpc/types.h: No such file or directory
compilation terminated.
make: *** [$objdir/sunrpc/cross-rpc_clntout.o] Error 1
Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Subject: [PATCH] Fix segmentation fault in strncasecmp for i686
2012-08-15 Liubov Dmitrieva <liubov.dmitrieva@gmail.com>
[BZ #14195]
* sysdeps/i386/i686/multiarch/strcmp-sssse3.S: Fix
segmentation fault for a case of two empty input strings.
* string/test-strncasecmp.c (check1): Renamed to...
(bz12205): ...this.
(bz14195): Add new testcase for two empty input strings and N > 0.
(test_main): Call new testcase, adapt for renamed function.
