This is not completely correct.  With the patch above being checked in now the
'compile' command will still fail on:

$ 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.

It would need some special exception.

So far it is obvious that one needs gcc-5.0 which "nobody" has.  But after
gcc-5.0 gets released MinGW gdb.exe will still print "Could not load libcc1.so"
while (I expect) MinGW gcc-5.0 will have "libcc1.dll".
