Update.
2003-12-17  Carlos O'Donell  <carlos@baldric.uwo.ca>

	* sysdeps/hppa/fpu/fclrexcpt.c (feclearexcept): Right shift
	FE_ALL_EXCEPT before complimenting.
	* sysdeps/hppa/fpu/fegetenv.c (fegetenv): Use asm 'ma,' completer,
	and gcc '+r' constraint.
	* sysdeps/hppa/fpu/feholdexcpt.c (feholdexcept): Likewise.
	* sysdeps/hppa/fpu/fesetenv.c (fesetenv): Likewise.
	* sysdeps/hppa/fpu/feupdateenv.c (feupdateenv): Read raised
	exception bits, OR with envp, pass to fesetenv.
	* sysdeps/hppa/fpu/fraiseexcpt.c (feraiseexcept): Add delayed
	exception flushing, FE_UNDERFLOW is DBL_MIN/3.0, FE_INEXACT is
	triggered by M_PI/69.69 converted to single precision.
	* sysdeps/hppa/fpu/fsetexcptflg.c (fesetexceptflag): Set enable
	bits not raised exception bits.

	* sysdeps/hppa/Makefile: Add dl-symaddr and dl-fptr to the
	correct build strings.
	* sysdeps/hppa/dl-fptr.h: New file.
	* sysdeps/hppa/dl-fptr.c: Removed.
	* sysdeps/hppa/dl-symaddr.c (_dl_symbol_address): Use _dl_make_ftpr,
	remove const qualifier for map.
	(_dl_function_address): Removed.
	* sysdeps/hppa/dl-lookupcfg.h: DL_LOOKUP_ADDRESS must clear
	PLABEL32 bits, define DL_AUTO_FUNCTION_ADDRESS and
	DL_STATIC_FUNCTION_ADDRESS, DL_DT_INIT_ADDRESS and
	DL_DT_FINI_ADDRESS use the previous two macros.

	* misc/mntent_r.c: Change encoding to match recently changed decoder.
