[libstdc++, 3.3?] Fix --enable-cxx-flags

[Phil Edwards]

When this file was last edited, Benjamin accidentally put the ending ')'
of AC_ARG_ENABLE too early.  The resulting logic was, "if this option was
given, set it to off."  :-)

The relevant part of the patch is given below.  I also removed trailing
whitespace throughout the file, which makes for a large and boring diff.

Tested on i686/linux gnu, no problems, and applied to trunk.  I think
the bug is also on the 3.3 branch but haven't checked yet.  If it is,
I'll test and commit the same fix there.


2002-12-30  Phil Edwards  <pme@gcc.gnu.org>

	* acinclude.m4:  Remove trailing whitespace.
	(GLIBCPP_ENABLE_CXX_FLAGS):  Fix.
	* aclocal.m4, configure:  Regenerate.
