 Trying to get the source corresponding to the 20070904 Windows

 Between them, they don't seem to be the complete source of the
 binary distribution I have installed.

Well, they are complete, except for the special collect2, which is a contribution, and therefore is not part of the main gpc sources.

 I can't find any reference to "winmain", which I'm sure is involved
 in a Windows GUI application.

No, it isn't - certainly, not when compiled with gpc. If you're going to do it all manually, then just supply "-mwindows" and everything should be okay. You might also need to link the gdi32, comctl32, and comdlg32 libraries.

 The only version of "collect2" is in the "gcc" chain.  It doesn't
 invoke "windres", and it certainly doesn't say "ld-orig" when it
 can't find "ld".

The sources are in my "contrib" directory: http://www.gnu-pascal.de/contrib/chief/win32/mingw32/

 What do I need to download to be in a position to build GPC under
 and for Windows?

See above.
