* include/libc-symbols.h [!__ASSEMBLER__] (strong_alias):
Add extra level of macro expansion. [!__ASSEMBLER__ && HAVE_WEAK_SYMBOLS] (weak_alias): nLikewise. * sysdeps/generic/bp-thunks.h: Ensure `struct timeval' definition is available at the time `select' prototype is declared. * sysdeps/unix/make-syscalls.sh: Remove unused variables. Collect non-versioned weak aliases. Consider only non-versioned aliases for the user-visible systemcall name. Do checks inline with call to primitive system call. * sysdeps/unix/sysv/linux/ptrace.c (ptrace): Add void cast to stand-alone bounds checks to suppress unused value warnings. * sysdeps/unix/sysv/linux/sysctl.c (__sysctl): Likewise. 2000-07-11 Greg McGary <greg@mcgary.org> * include/libc-symbols.h [!__ASSEMBLER__] (strong_alias): Add extra level of macro expansion.
