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?


#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;
err = chmod(copy->base_string.self, S_IRWXU) < 0;
if (err) {
FElibc_error("Unable to give executable permissions to ~A",
    1, copy);
