The implementation of the (XSI POSIX) functions hsearch / hcreate / hdestroy uses hsearch_r / hcreate_r / hdestroy_r, which are not POSIX functions. This patch makes those into weak aliases for __*_r and uses those names for the calls within libc. Tested for x86_64 that the disassembly of installed shared libraries is unchanged by this patch. [BZ #17996] * include/search.h (hcreate_r): Don't use libc_hidden_proto. (hdestroy_r): Likewise. (hsearch_r): Likewise. (__hcreate_r): Declare and use libc_hidden_proto. (__hdestroy_r): Likewise. (__hsearch_r): Likewise. * misc/hsearch.c (hsearch): Call __hsearch_r instead of hsearch_r. (hcreate): Call __hcreate_r instead of hcreate_r. (__hdestroy): Call __hdestroy_r instead of hdestroy_r. * misc/hsearch_r.c (hcreate_r): Rename to __hcreate_r and define as weak alias of __hcreate_r. (hdestroy_r): Rename to __hdestroy_r and define as weak alias of __hdestroy_r. (hsearch_r): Rename to __hsearch_r and define as weak alias of __hsearch_r. * conform/Makefile (test-xfail-XPG3/search.h/linknamespace): Remove variable. (test-xfail-XPG4/search.h/linknamespace): Likewise. (test-xfail-UNIX98/search.h/linknamespace): Likewise. (test-xfail-XOPEN2K/search.h/linknamespace): Likewise. (test-xfail-XOPEN2K8/search.h/linknamespace): Likewise.
