Ok, hmm.. don't touch $(topsrcdir)/configure{.in}

Then looks like the patch, I mentioned at the start of this thread,
didn't/doesn't work here.

2001-03-27  Alexandre Oliva  <aoliva@redhat.com>

        * configure.in (CXX_FOR_TARGET): Use xgcc for libstdc++-v3.
		 
My bootstraps have been failing since that day. There are some related
changes inside libstdc++-v3:

2001-03-28  Alexandre Oliva  <aoliva@redhat.com>

        * libsupc++/Makefile.am (CXXLINK): Add --tag disable-shared
		* after --tag CXX.
		(LIBTOOL): Let automake take care of its definition.
		* libsupc++/Makefile.in: Rebuilt.

2001-03-27  Alexandre Oliva <aoliva@redhat.com>

		* libsupc++/Makefile.am
		* (CXXLINK): Use CXX again, and
		* choose CXX tag explicitly.
		* src/Makefile.am
		* (CXXLINK):
		* Likewise.
		* libsupc++/Makefile.in,
		* src/Makefile.in:
		* Rebuilt.

Ever since then: (build.log excerpt of it using g++ to link...)

 I know it's ugly.. and rather long, but build.logs tend to be.

 My problem is then, how does it work for anyone else? I use a clean
 builddir != srcdir. Was bootstrapping daily just fine, until the above
 changes.
