mq_receive calls mq_timedreceive, and mq_send calls mq_timedsend. But mq_receive and mq_send were in POSIX by 1996, while mq_timed* were added in the 2001 edition of POSIX. This patch fixes this by making mq_timed* into weak aliases for __mq_timed* and calling the __mq_timed* names. Tested for x86_64 and x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #18545] * rt/mq_timedreceive.c (mq_timedreceive): Rename to __mq_timedreceive and define as alias of __mq_timedreceive. Use hidden_weak. * rt/mq_timedsend.c (mq_timedsend): Rename to __mq_timedsend and define as alias of __mq_timedsend. Use hidden_weak. * sysdeps/unix/sysv/linux/syscalls.list (mq_timedsend): Use __mq_timedsend as strong name. (mq_timedreceive): Use __mq_timedreceive as strong name. * include/mqueue.h (__mq_timedsend): Declare. Use hidden_proto. (__mq_timedreceive): Likewise. * sysdeps/unix/sysv/linux/mq_receive.c (mq_receive): Call __mq_timedreceive instead of mq_timedreceive. * sysdeps/unix/sysv/linux/mq_send.c (mq_send): Call __mq_timedsend instead of mq_timedsend. * conform/Makefile (test-xfail-UNIX98/mqueue.h/linknamespace): Remove variable.
