Here's the patch:
FYI, at first I thought it was a bug in gcc and reported it,
but Jakub Jelinek explained that it is a feature, and
suggested the work-around of using -P.

Subject: [PATCH] invoke $CPP with its -P option, to accommodate change in
latest gcc
* configure.in: Use $CPP's -P option when creating Makefile and
src/Makefile. This is required with at least by gcc 4.4.2, which
is part of fedora 12. Otherwise, each backslash-newline pair in
the input would be mistakenly converted to a bare newline, yielding
invalid Makefiles.
* configure: Regenerate.
