I am really puzzled. On re-reading your email I realized this problem was
actually located in the loader code, in a piece that is cygwin-specific.
This suggests that something has either changed on cygwin or that this
behavior depends on the version of the Windows you are using.

The code, shown below, (src/c/ffi/libraries.d) changes the extension of a
compiled file to turn it into a *.dll and also changes permissions, so that
cygwin can load it. Could you simply comment it out and try rebuilding?

Juanjo

#ifdef cygwin
{
cl_object new_copy = make_constant_base_string(".dll");
 new_copy = si_base_string_concatenate(2, copy, new_copy);
cl_rename_file(2, copy, new_copy);
 copy = new_copy;
}
ecl_disable_interrupts();
 err = chmod(copy->base_string.self, S_IRWXU) < 0;
ecl_enable_interrupts();
 if (err) {
FElibc_error("Unable to give executable permissions to ~A",
     1, copy);
}
#endif
