The getpass function (XPG3 / XPG4 / UNIX98) calls fflush_unlocked (not in any of those standards). This patch fixes this by making fflush_unlocked into a weak alias for __fflush_unlocked and calling __fflush_unlocked from getpass. Tested for x86_64 and x86 (testsuite, and that disassembly of installed stripped shared libraries is unchanged by the patch). [BZ #18540] * libio/iofflush.c [!_IO_MTSAFE_IO] (__fflush_unlocked): Define as strong alias of _IO_fflush. Use libc_hidden_def. * libio/iofflush_u.c (fflush_unlocked): Rename to __fflush_unlocked and define as weak alias of __fflush_unlocked. Use libc_hidden_weak. * include/stdio.h (__fflush_unlocked): Declare. Use libc_hidden_proto. * misc/getpass.c (getpass): Call __fflush_unlocked instead of fflush_unlocked. * conform/Makefile (test-xfail-UNIX98/unistd.h/linknamespace): Remove variable.
