Ulrich Drepper ae1025be40 Updated.
1997-06-26 21:50  Ulrich Drepper  <drepper@cygnus.com>

	* math/math.h: Move definition of macros for unordered comparison
	after inclusion of <bits/mathinline.h>.
	* sysdeps/i386/fpu/bits/mathinline.h: Don't undef macros for
	unordered comparison before definition.
	* sysdeps/m68k/fpu/bits/mathinline.h: Likewise.

	* Makerules: Move definition of load-map-file before use.
	(lib%.so): Depend on load-map-file, not lib%-map.

	* manual/lgpl.texinfo: Likewise.

1997-06-24 09:40  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/m68k/fpu/bits/mathinline.h: Don't define __ilogb.
	* sysdeps/m68k/fpu/s_ilogb.c: Define it here.  Handle zero, NaN

	Adapted.

	* sysdeps/m68k/fpu/bits/mathdef.h (FP_ILOGB0): Correct value.

1997-06-26 17:06  Ulrich Drepper  <drepper@cygnus.com>

	* configure.in: Don't use .long in tests since some strange
	platforms without binutils don't know this.
	Redirect output of test commands correctly.
	Patch by Klaus Espenlaub <kespenla@hydra.informatik.uni-ulm.de>.

	* hurd/hurdsig.c (_hurdsig_init): Call _hurd_self_sigstate.
	Patch by Kazumoto Kojima <kkojima@kk.info.kanagawa-u.ac.jp>.

	* sysdeps/mach/hurd/open.c (__open): Fix type of parameter file.

	* sysdeps/mach/hurd/sysd-stdio.c (__stdio_reopen): Add closefn to
	paramater list since it is used.

	* sysdeps/mach/hurd/rename.c (rename): Fix type of paramater new.

	* sysdeps/mach/hurd/sigaltstack.c (sigaltstack): Change parameter from
	ss to argss.
