Update.

1999-10-18  Andreas Jaeger  <aj@suse.de>

	Added improved math testsuite:
	* math/libm-test.inc: New file, contains all tests from
	libm-test.c but in a different form.
	* math/libm-test.c: Removed.
	* sysdeps/generic/libm-test-ulps: New file: Fallback ulps file.
	* math/gen-libm-test.pl: New file: Preprocessor.
	* math/test-double.c: Adopted to new testsuite.
	* math/test-idouble.c: Likewise.
	* math/test-float.c: Likewise.
	* math/test-ifloat.c: Likewise.
	* math/test-ldouble.c: Likewise.
	* math/test-ildoubl.c: Likewise.
	* math/Makefile: Added rules to generate new suite.
