Update.

1998-05-31  Philip Blundell  <philb@gnu.org>

	* sysdeps/unix/sysv/linux/arm/sysdep.S: Use C_SYMBOL_NAME when
	referring to errno and _errno.

	* sysdeps/arm/fpu/feholdexcpt.c: New file.

	* sysdeps/i386/fpu_control.h: Fix typo.

	* sysdeps/arm/bits/setjmp.h (__jmp_buf): Remove floating-point support.
	(_JMPBUF_UNWINDS): Added.
	* sysdeps/arm/fpu/bits/setjmp.h: New file.

1998-05-25  Gordon Matzigkeit  <gord@profitpress.com>

	* sysdeps/mach/hurd/Makefile: Use the `before-compile' target in
	order to build header files, not `generated'.

	* Rules (before-compile): New target which depends on all
	$(before-compile) files.
