	once.

	.text and .previous to select correct section.

1997-09-23 19:56  Philip Blundell  <Philip.Blundell@pobox.com>

	* configure.in: Add `--disable-versioning' option to suppress the

	* sysdeps/powerpc/dl-machine.h: Prepare for library profiling.

	* sysdeps/powerpc/bits/mathinline.h: Add slightly slower versions
	of the C9X FP comparison macros. Delete 'fabs' and 'sqrt' inline
	routines, because gcc has them as internals.

	* math/libm-test.c (exp2_test): Add some more tests.

	* Rules: Use empty.os instead of empty.o, since it gets linked into
	libc.so...
	* configure.in: Add --disable-static to disable building .a files.
	* config.make.in: Substitute the new variable.
	* Makeconfig: Don't build .o files if not building .a files.

	* posix/globtest.c (main): Change to directory passed as first
	argument.

	* posix/globtest.sh: Don't cd before running the program, instead
