(We had quite some problems getting it to work on Cygwin at all with GCC, but it turned out that libtool could not identify whether shared libraries worked or not because of a missing "file" command. At least that seemed to be the main cause.) Anyway, the message is clear - we will refrain from shared libraries for Fortran 95 at the moment.
