Use 1 in this case. * sysdeps/i386/dl-machine.h (elf_machine_load_address): Use notation for local label. * time/strftime.c (add): Respect `0' padding flag. Reported by Richard Stallman . 1997-04-30 15:46 Ulrich Drepper * Makeconfig (start-installed-name): Define here, not in csu/Makefile. Use in +link macro. * csu/Makefile (distribute): Add abi-note.S and abi-tag.h. (start-installed-name): Don't define here.

Patches by Roland McGrath . 1997-04-30 01:32 Ulrich Drepper * manual/stdio.texi: Use @vtable where possible. Add TeX version of @multitable since texi2dvi cannot handle them correct in the moment. * po/de.po: Update. 1997-04-29 21:06 Ulrich Drepper * Makeconfig: Don't set cross-compiling based on $(BUILD_CC) != $(CC). * config.make.in: Set cross-compiling from configure result. * configure.in: Emit definition of `cross_compiling'.
