Update.
1998-04-07 Ulrich Drepper <drepper@cygnus.com> * configure.in: Recognize --with-headers flag and determine commandline options to be used in compilation. * Makeconfig (+includes): Use $(sysincludes). * config.make.in (sysincludes): Define from SYSINCLUDES. * glibcbug.in: Use SYSINCLUDES information. Patches by Zack Weinberg. * sysdeps/sparc/sparc32/elf/start.S: Rewrite for __libc_start_main. * sysdeps/sparc/sparc64/elf/start.S: Likewise.
