Interesting! This is best added to the 'compile' script which is "owned" by Automake, so I have added a CC. At one point I posted a hacked version of 'compile' to the libffi list, but it relied on a separate preprocessing step, followed by directly invoking the assembler (ml.exe). See the attachment in http://sourceware.org/ml/libffi-discuss/2012/msg00144.html It seems very nice to get rid of the extra preprocessing step. However, I can't get assembly to actually work with -Tc or -TC (see below), so what am I doing wrong?
