configure.in: Fix cross compiling math routines.

Browse source 
2001-09-10  Benjamin Kosnik  <bkoz@redhat.com>

	* configure.in: Fix cross compiling math routines. Correct
	comments for cross compiling and limits. Add floating point math
	routines found in newlib.
	* configure: Regenerate.
	* acconfig.h: Add macros.
	* config.h.in: Regenerate.

# This lets us hard-code the functionality we know

# sugar-coated word placed on an especially dull and tedious hack, actually.
# Here's why GLIBCPP_CHECK_MATH_SUPPORT, and other autoconf macros
# that involve linking can't be used:
# "cannot open sim-crt0.o"
# "cannot open crt0.o"
# etc. All this is because there currently exists no unified,
# consistent way for top level CC information to be passed down
# to target directories: newlib includes, newlib linking info,
# libgloss versus newlib crt0.o, etc. When all of this is done, all
# of this hokey, excessive AC_DEFINE junk for crosses can be removed.
# We are being configured with some form of cross compiler.
# mknumeric_limits may not work correctly, either because the
# compiler may not run on this machine, may not be able to link
# executables, or may produce executables we can't run on this
# machine. Thus, just use the pre-generated include/bits/limits_generic.h
