+       * generate.py (codeargs): Add cygwin case to link against libmingwex.
+       This is a little tricky as _ufinc.dll needs to be linked against
+       libmingwex, but libnumarray.dll normally picks up wrong symbols from
+       this library. Therefore we explicitely add libm, libc, and libgcc before
+       the mingw libraries to avoid the latter and still have them available to
+       resolve the FE symbols. We also explicitely have to add -L/lib before
+       -L/lib/mingw to check for normal cygwin libraries first.
