	* 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.

	* 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>

	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.
