The build on mingw host is broken because mingw has no mkdtemp.

In the end I have managed to test it by Wine myself:

$ wine build_win32/gdb/gdb.exe -q build_win32/gdb/gdb.exe -ex start -ex 'compile code 1' -ex 'set confirm no' -ex quit
[...]
Temporary breakpoint 1, main (argc=1, argv=0x241418) at ../../gdb/gdb.c:29
29        args.argc = argc;
Could not load libcc1.so: Module not found.

Even if it managed to load libcc1.so (it needs host-dependent name libcc1.dll)
then it would soon end up at least on:

default_infcall_mmap:
  error (_("This target does not support inferior memory allocation by mmap."));

As currently there is only:

linux-tdep.c:
  set_gdbarch_infcall_mmap (gdbarch, linux_infcall_mmap);

While one could debug Linux targets from MS-Windows host I find it somehow
overcomplicated now when we are trying to get it running at least on native
Linux x86*.

The 'compile' project needs a larger port effort to run on MS-Windows.
