[csw-maintainers] Problems compiling ctypes on Solaris x86

[Maciej (Matchek) Blizinski]

The ctypes Python module compiles on sparc, but not on x86.  The error
message is:

"build/temp.solaris-2.9-i86pc-2.6/libffi/include/ffitarget.h", line
67: undefined symbol: FFI_DEFAULT_ABI

pkg-config seems to be doing the right thing:

 > pkg-config --cflags-only-I libffi
-I/opt/csw/lib/libffi-3.0.8/include

I'm not sure how does ffitarget.h end up in the
build/temp.solaris-2.9-i86pc-2.6/libffi/include, but these two are
exactly the same:

work/solaris9-i386/build-isa-i386/Python-2.6.5/build/temp.solaris-2.9-i86pc-2.6/libffi/include/ffitarget.h
/opt/csw/lib/libffi-3.0.8/include/ffitarget.h

...so I conclude the Python build system makes a copy.

So why does it error out?  An unfortunate combination of flags
perhaps?  Is this a known problem with libffi?
