I will have a look, thank you.

Not really an issue. Also making under mingw/cygwin is fine, if it
produces libs/dlls with msvc readable symbols.

There has to be room for further improvements ;-)

But seriously, I think that a debug build that's buildable by standard
configure/make plus some icl specific configure switches would really
be a huge improvement and would be very helpful, especially for
understanding ffmpeg.

Regarding the release build and inline assembler, that's future music.
If the above would attract new developers coming from windows then
perhaps someone would work on the release build also.

All the best
