1997-06-29 23:43  Ulrich Drepper  <drepper@cygnus.com>

	* config.make.in: Define need-nopic-initfini.
	* configure.in: Write out nopic_initfini.
	* csu/Makefile: Generate no-PIC crt code if need-nopic-initfini
	is defined.

	* sysdeps/i386/fpu/fraiseexcpt.c: Correct FE_INEXACT case.

	* sysdeps/sparc/rem.S: Get trap definition properly.
	* sysdeps/sparc/sdiv.S: Likewise.
	* sysdeps/sparc/udiv.S: Likewise.
	* sysdeps/sparc/urem.S: Likewise.
	* sysdeps/sparc/setjmp.S: Include <sys/trap.h>.
	* sysdeps/sparc/sys/trap.h: New file.
	* sysdeps/unix/sysv/linux/sparc/sys/trap.h: New file.

1997-06-25 10:26  Thorsten Kukuk  <kukuk@uni-paderborn.de>

	* sysdeps/generic/rpc/auth.h: Add xdr_opaque_auth declaration.

1997-06-29 10:34  Fila Kolodny  <fila@ibi.com>

	* sysdeps/mach/hurd/select.c (__select): Change MACH_MSG_SIZE_INTEGER_T
	to MACH_MSG_TYPE_INTEGER_T.

1997-06-29  01:04  Richard Henderson  <richard@gnu.ai.mit.edu>

	Initial sparc64-linux support:
	* configure.in: Recognize sparc64 as being different from sparc.
	* io/ftwtest-sh: Only invoke ld.so if it exists.
	* math/Makefile (LDLIBS-*): Change from libm to math/libm to get
	static tests to link.  Honour $(omit-long-double-fcts) == yes.
	* math/libm-test.c (test_single_exception): The argument to
	fetestexcept is `int' not `fexcept_t'.
	* shlib-versions: Recognize sparc64.
	* signal/signal.h: Add typedef for stack_t.

	* stdio-common/_itoa.c: Defaulting UMUL_TIME==UDIV_TIME is broken.
	Attempt to fix up most of this by cleaning up assumptions below,
	but give up and change the defaults.

	* setjmp/longjmp.c: Moved to ...
	* sysdeps/generic/longjmp.c: ... here.
	* setjmp/sigjmp.c: Moved to ...
	* sysdeps/generic/sigjmp.c: ... here.

	* sysdeps/sparc/bsd-_setjmp.S [PIC]: There wasn't even valid asm here.
	Ought to fix up gas to catch these silly things properly.
	* sysdeps/sparc/bsd-setjmp.S: Likewise.

	* sysdeps/unix/sysv/linux/sparc/errno.c: Remove.
	* sysdeps/unix/sysv/linux/sparc/kernel_sigaction.h: Remove.
	* sysdeps/unix/sysv/linux/sparc/kernel_stat.h: Tell xstat about
	the unused fields.

	* sysdeps/sparc/sparc64/add_n.s: Moved to ...
	* sysdeps/sparc64/add_n.S: ... here.  Fix up %g4 and stack usage.
	* sysdeps/sparc/sparc64/addmul_1.s: Likewise.

1997-06-28 16:28  H.J. Lu  <hjl@gnu.ai.mit.edu>

	* configure.in: Add -nostartfiles -nostdlib when check for
	--version-script.
