Roland McGrath 564210fe2f Mon Jun 10 02:22:24 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* sysdeps/unix/sysv/linux/configure.in: New file, start with configure.
	Add check for installed <linux/version.h> being v2.0 or later.

	* sysdeps/generic/dl-sysdep.c (_dl_sysdep_open_zero_fill): Call __open
	instead of open.
	(_dl_sysdep_fatal): Call __write instead of write.
	(_dl_sysdep_message): Likewise.

Sun Jun  9 20:40:00 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/m68k/fpu/e_acosl.c: New file.

	* Makerules (o-objects): New variable.  Use it in place of
	$(objects:.o=$o); it filters out $(elide-routines$o).
	Use o-iterator for ar and ranlib rules so they use the per-type object
	list.

	* sysdeps/unix/bsd/ultrix4/sys/mman.h: Likewise.
