libffi@3.0.9_0+universal installes an invalid ffitarget.h

[yugui@…]

I installed libffi@3.0.9_0 with +universal variant on MacOS X 10.5, and I got an invalid /opt/local/lib/libffi-3.0.9/include/ffitarget.h .

I did as the following:

% uname -a
Darwin yugui-macbookpro.local 9.8.0 Darwin Kernel Version 9.8.0: Wed Jul 15 16:55:01 PDT 2009; root:xnu-1228.15.4~1/RELEASE_I386 
% port version
Version: 1.9.1
% sudo port install libffi +universal universal_archs="i386 ppc x86_64"

After installation succeeded, I got the attached ffitarget.h as /opt/local/lib/libffi-3.0.9/include/ffitarget.h. This file is not valid for C preprocessor, So preprocessing for the following C source fails.

conftest.c:

#include <ffi.h>
int main(void){ return 0; }

preprocessing:

% /usr/bin/gcc -E -I/opt/local/include -I/opt/local/lib/libffi-3.0.9/include -o conftest.i conftest.c
In file included from /opt/local/lib/libffi-3.0.9/include/ffi.h:68,
                 from conftest.c:1:

It seems to have tried merging src/x86/ffitarget.h and src/powerpc/ffitarget.h and to have generates a wrong ffitarget.h.
