gengetopt with native Win32 CL.EXE

[Andreas Baumann-3]

Hi,


I tried to produce the C and header files from a GGO file for native
Windows compilation with CL.EXE. Using any of the Cygwin or MinGW ports
of 'gengen` and 'gengetopt` as built-chain works.

As I see it, there is a small problem in the generated C code with the
FIX_UNUSED macro which is sometimes called before or in the middle of a
variable declaration in generated functions.

After patching with gengetopt-2.22.2-fix-unused.patch, compilation is no problem.

Greetings

Andreas

Ah, perfect. :-)

Yes, the patch corrects exactly the same lines as in 2.22.3.
Works fine.

Thanks
