Sure. BTW winapi_extract can already do that:
This generates a .spec2 file that should hopefully be the same as
the .spec file. It currently isn't (except for a few files) though
but that can hopefully be fixed.
Outputing in another format like .def files or
whatever should be quite easy.
However note that winapi_extract is quite ad hoc and specfic for
parsing the Wine source tree. It is not a generalized C parser.
I have begun with a generalized C parser in winapi_fixup however
it doesn't quite work that good yet. Parsing generalized C
is non trivial.

Agreed, but the script that does it is also a potential source of mistake
and the current state of the winapi tools are that they work MOST of
the time. However if we are to replace the .spec files it must work
ALL the time.
However I might be able to write a very specialized parser, that
pipes the .c files through the C preprosessor, that work all of the
time, but this is quite some work as well.
Note however that piping every source file through the C prepropessor
is VERY SLOW. That is one of the reason the winapi tools doesn't
