regcomp brings in references to various wctype functions that aren't in all the standards including regcomp. This patch fixes this in the usual way by using the __* versions of these functions (which already exist, but some didn't have libc_hidden_proto / libc_hidden_def before). Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). (Other wide character function references from the regex code mean that this patch by itself doesn't fix any XFAILed linknamespace test failures; further patches will be needed for that.) [BZ #18495] * wctype/wcfuncs.c (__iswalnum): Use libc_hidden_def. (__iswlower): Likewise. * include/wctype.h (__iswalnum): Declare. Use libc_hidden_proto. (__iswlower): Likewise. * posix/regcomp.c (re_compile_fastmap_iter): Call __towlower instead of towlower. * posix/regex_internal.c (build_wcs_upper_buffer): Call __iswlower instead of iswlower. Call __towupper instead of towupper. * posix/regex_internal.h (IS_WIDE_WORD_CHAR): Call __iswalnum instead of iswalnum.
