pathconf uses __statvfs64, and fpathconf uses __fstatvfs64. On systems using sysdeps/unix/sysv/linux/wordsize-64, __statvfs64 then brings in the strong symbol statvfs, and __fstatvfs64 brings in the strong symbol fstatvfs, which are not in all the standards that have pathconf and fpathconf. This patch fixes this by making those symbols into weak aliases. Tested for x86_64 and x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #18507] * sysdeps/unix/sysv/linux/fstatvfs.c (fstatvfs): Rename to __fstatvfs and define as weak alias of __fstatvfs. Use libc_hidden_weak. * sysdeps/unix/sysv/linux/statvfs.c (statvs): Rename to __statvfs and define as weak alias of __statvfs. Use libc_hidden_weak. * sysdeps/unix/sysv/linux/wordsize-64/fstatvfs.c (__fstatvfs64): Define as alias of __fstatvfs, not fstatvfs. (fstatvfs64): Likewise. * sysdeps/unix/sysv/linux/wordsize-64/statvfs.c (__statvfs64): Define as alias of __statvfs, not statvfs. (statvfs64): Likewise. * conform/Makefile (test-xfail-POSIX/unistd.h/linknamespace): Remove variable.
