Hi again. I dug into my problem, and I've managed to solve it.
It seems that all the functions above are not defined as symbols
in libmingw32.a. There are in libcygwin.a, but also are in other
various libraries (libmoldname.a, libcrtdll.a, ...). I added
those libraries to my dllwrap command line, and now it works
(I can run my program without cygwin1.dll).
That looks a little bit strange to me (I would have expected that
because of the --m-no-cygwin flag, dllwrap would complain about
abort, ..., being undefined references, instead of linking with
libcygwin.a). Can anyone comment ?
