Tue Mar 12 04:42:01 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu>
	* sysdeps/sparc/jmp_buf.h: Rewritten; use array of ints, not struct.
	* sysdeps/sparc/setjmp.S: Rewritten; store %fp value as well.
	* sysdeps/sparc/__longjmp.S: Rewritten; unwind frames one by one with
	`restore' until the target frame is hit.

Sun Mar 10 20:29:40 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/sigsuspend.c: New file.
	* sysdeps/unix/sysv/linux/syscalls.list: Remove sigsuspend, add
	s_sigsuspend.

Thu Mar  7 21:30:58 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* Makerules (+make-deps, sed-remove-objpfx): Quote periods on the
	left side of sed substitutions.

Sun Mar 10 16:58:10 1996  Ulrich Drepper  <drepper@gnu.ai.mit.edu>

	* stdio-common/printf_fp.c (hack_digit): __mpn_normal_size
	is not available anymore.  Do it ourselves.

	* sysdeps/unix/sysv/linux/i386/fpu_control.h (_FPU_SETCW):
	Correct GCC `asm' syntax.

	* stdio-common/Makefile (tests): Add tst-ungetc.
	* stdio-common/tst-ungetc.c: New test from drepper.
	* stdio-common/tstscanf.c (main): New %[ test case from drepper.

	* sysdeps/libm-ieee754/s_scalbn.c (scalbn): Rename to __scalbn;
	somehow this was missed, though the weak alias is already there.
