ttyslot (XPG4) calls the non-XPG4 functions endttyent, getttyent and setttyent, which in turn bring in references to fgets_unlocked and getttynam. This patch fixes this by making these functions into weak aliases and calling the __* names as needed. Tested for x86_64 and x86 (testsuite, and that disassembly of installed stripped shared libraries is unchanged by the patch). [BZ #18547] * misc/getttyent.c (getttynam): Rename to __getttynam and define as weak alias of __getttynam. Use prototype function definition. Call __setttyent, __getttyent and __endttyent instead of setttyent, getttyent and endttyent. (getttyent): Rename to __getttyent and define as weak alias of __getttyent. Call __setttyent instead of setttyent. Call __fgets_unlocked instead of fgets_unlocked. (setttyent): Rename to __setttyent and define as weak alias of __setttyent. (endttyent): Rename to __endttyent and define as weak alias of __endttyent. * include/ttyent.h (__getttyent): Declare. Use libc_hidden_proto. (__setttyent): Likewise. (__endttyent): Likewise. (getttyent): Don't use libc_hidden_proto. (setttyent): Likewise. (endttyent): Likewise. * misc/ttyslot.c (ttyslot): Call __setttyent, __getttyent and __endttyent instead of setttyent, getttyent and endttyent. * conform/Makefile (test-xfail-XPG4/unistd.h/linknamespace): Remove variable.
