Fix regcomp wcscoll, wcscmp namespace (bug 18497).
regcomp brings in references to wcscoll, which isn't in all the standards that contain regcomp. In turn, wcscoll brings in references to wcscmp, also not in all those standards. This patch fixes this by making those functions into weak aliases of __wcscoll and __wcscmp and calling those names instead as needed. Tested for x86_64 and x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #18497] * wcsmbs/wcscmp.c [!WCSCMP] (WCSCMP): Define as __wcscmp instead of wcscmp. (wcscmp): Define as weak alias of WCSCMP. * wcsmbs/wcscoll.c (STRCOLL): Define as __wcscoll instead of wcscoll. (USE_HIDDEN_DEF): Define. [!USE_IN_EXTENDED_LOCALE_MODEL] (wcscoll): Define as weak alias of __wcscoll. Don't use libc_hidden_weak. * wcsmbs/wcscoll_l.c (STRCMP): Define as __wcscmp instead of wcscmp. * sysdeps/i386/i686/multiarch/wcscmp-c.c [SHARED] (libc_hidden_def): Define __GI___wcscmp instead of __GI_wcscmp. (weak_alias): Undefine and redefine. * sysdeps/i386/i686/multiarch/wcscmp.S (wcscmp): Rename to __wcscmp and define as weak alias of __wcscmp. * sysdeps/x86_64/wcscmp.S (wcscmp): Likewise. * include/wchar.h (__wcscmp): Declare. Use libc_hidden_proto. (__wcscoll): Likewise. (wcscmp): Don't use libc_hidden_proto. (wcscoll): Likewise. * posix/regcomp.c (build_range_exp): Call __wcscoll instead of wcscoll. * posix/regexec.c (check_node_accept_bytes): Likewise. * conform/Makefile (test-xfail-XPG3/regex.h/linknamespace): Remove variable. (test-xfail-XPG4/regex.h/linknamespace): Likewise. (test-xfail-POSIX/regex.h/linknamespace): Likewise.
