* malloc/memalign.c: Allocate (SIZE + ALIGNMENT - 1) and then trim if possible. * mach/shortcut.awk: Emit decls for RPC. * libc-symbols.h [GCC >= 2.7 && !ASSEMBLER] (weak_symbol, weak_alias, strong_alias): Define using GCC __attribute__ syntax. * Makerules ($(installed-libcs)): Depend on `lib' (only).
