Update.cvs/libc-ud-970614

1997-06-15 00:43  Ulrich Drepper  <drepper@cygnus.com>

	* Makeconfig: Define libc-map here.
	* Makefile: And remove definition here.
	* Makerules (load-map-file): Handle case where map file is in
	other directory.
	(build-shlib): Likewise.

	* libc.map: Add more symbols.
	* resolv/libresolv.map: Likewise.

	* db/libdb.map: Add __dbopen.  Patch by HJ Lu.

	* libio/stdio.h: Remove "optmizations" for vfscanf and vsscanf.

	* locale/programs/localedef.c: Add normalize_codeset function.  We
	don't want to use the _nl_normalize_codeset functions from libc.

	* sysdeps/libm-i387/s_asinh.S: Handle +-Inf and NaN correctly.
	* sysdeps/libm-i387/s_asinhf.S: Likewise.
	* sysdeps/libm-i387/s_asinhl.S: Likewise.
	* sysdeps/libm-i387/s_nearbyint.S: Correctly leave function.
	* sysdeps/libm-i387/s_nearbyintf.S: Likewise.
	* sysdeps/libm-i387/s_nearbyintl.S: Likewise.

1997-06-14 12:45  Thorsten Kukuk  <kukuk@vt.uni-paderborn.de>

	* nis/nss_nis/nis-ethers.c: Add static to internal_nis_setetherent.

	* nis/nss_nis/nis-proto.c: Add static to internal_nis_setprotoent.

	* nis/nss_nisplus/nisplus-hosts.c: Rewrite parser and fix
	_nss_nisplus_gethostbyaddr_r interface.

	* nis/libnsl.map: Add all GLOBAL functions.

1997-06-13 18:32  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* libm-test.c 	(main): Call new tests, reorder tests.
	(fmod_test): Test function fmod.
	(nearbyint_test): Test function nearbyint.
	(acos_test): Add more test cases.
	(signbit_test): Test macro signbit.
	(output_result_bool): Output result if test fails.
	(asin_test): Add another test case.
	(atan2_test): Add more tests.
	(asinh_test): Add more tests.
	(atanh_test): Add more tests.
	(hypot_test): Add more tests.
	(isfinite_test): Test macro isfinite.
	(isnormal_test): Test macro isnormal.
	(sincos_test): Tests for sincos.
	(main): Enable remquo_test since the tests are
	correct (according to ANSI/IEEE 754-1985).
	(remquo_test): Corrected tests cases and added more tests.
	(remainder_test): Tests for remainder.
	(check_int): New Function to compare int values.
	(check_isnan_exc_ext): New function.
	(sqrt_test): Add some extra tests for sqrt.
	(erf_test): Tests for erf.
	(erfc_test): Tests for erfc.
	(gamma_test): Tests for gamma.
	(lgamma_test): Tests for lgamma.

1997-06-08 10:54  H.J. Lu  <hjl@gnu.ai.mit.edu>

	* sysdeps/unix/sysv/linux/configure.in: Try to generate
	stdio_lim.h using the target C preprocessor and mk-stdiolim.c.
	* sysdeps/unix/sysv/linux/stdio_lim.h.in: New, template for
	stdio_lim.h.
	* sysdeps/unix/sysv/linux/mk-stdiolim.c: New, used by the
	target C preprocessor to extract OPEN_MAX and PATH_MAX.

1997-06-14 17:32  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* math/libm.map: Add inline functions, global variables.
