Fix __getcwd rewinddir namespace (bug 17584).
__getcwd is called from dcigettext.o (brought in by various ISO C functionality), but calls rewinddir, which is not an ISO C function. This patch makes __getcwd call __rewinddir instead and makes rewinddir a weak alias for __rewinddir. Since getcwd.c is shared with gnulib (albeit not merged in either direction for a long time, and omitted from gnulib's config/srclist.txt list of shared files) I put in a #ifndef _LIBC define of __rewinddir to rewinddir, although a future merged version of getcwd could end up looking significantly different. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by this patch). [BZ #17584] * dirent/rewinddir.c (rewinddir): Rename to __rewinddir and define as weak alias of __rewinddir. Don't use libc_hidden_def. (__rewinddir): Use libc_hidden_def. * sysdeps/mach/hurd/rewinddir.c: Rename to __rewinddir and define as weak alias of __rewinddir. Don't use libc_hidden_def. (__rewinddir): Use libc_hidden_def. * sysdeps/posix/rewinddir.c: Rename to __rewinddir and define as weak alias of __rewinddir. Don't use libc_hidden_def. (__rewinddir): Use libc_hidden_def. * include/dirent.h (rewinddir): Don't use libc_hidden_proto. (__rewinddir): Use libc_hidden_proto. * sysdeps/posix/getcwd.c [!_LIBC] (__rewinddir): Define to rewinddir. (__getcwd): Use __rewinddir instead of rewinddir.
