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.
