bug#5047: 23.1; emacs is failing to build on Fedora 12 64 bit

[Jan Djärv]

Ah, I tested with Emacs from CVS head.  This has been fixed there:

2009-10-23  Jim Meyering  <meyering@redhat.com>

        * configure.in: Invoke $CPP with -P when creating Makefile and
        src/Makefile.  Without this, gcc 4.4.2 converts each
        backslash-newline pair in the input to a bare newline, yielding
        invalid Makefiles.

Running
% CPPFLAGS=-P ./configure ...

works. This is what you have to do until 23.2 comes out.
