(strcpy): Don't optimize for gcc 3.0+. (__stpcpy): For gcc 3.0+, don't use __stpcpy_small but instead use __builtin_strcpy (, src) + strlen (src) for short string literal src. 2002-01-23 Jeroen Dobbelaere <jeroen.dobbelaere@acunia.com> * sysdeps/unix/sysv/linux/configure.in (libc_cv_gcc_unwind_find_fde): Set for arm, too. 2001-01-22 Paul Eggert <eggert@twinsun.com> * manual/llio.texi (Linked Channels, Cleaning Streams): Make it clearer that a just-opened input stream might need cleaning. 2002-01-21 H.J. Lu <hjl@gnu.org> * sysdeps/mips/dl-machine.h (ELF_MACHINE_BEFORE_RTLD_RELOC): Don't use label at end of compound statement.
