1.a) static library: sure.
  
  $ gcc -c foo1.c foo2.c
  $ ar crv libfoo.a foo1.o foo2.o

1.b) link directly with MSVC? Maybe, but before that you need to download
  the msvc40 runtime. Mingw as distributed uses CRTDLL runtime, but MSVC
  uses MSVCRT40.DLL. See my ftp area:
    ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/mingw32/egcs-1.1.1/
  
  Even with this, there may be incompatibilities (one of them I know of
  __chkstk vs __chkstk). Feel free to experiment and let us know. You
  may need to name the archive, ie., static library, with .lib extension.

  $ ar crv foo.lib foo1.o foo2.o

See above. Official answer is no (you can't even mix Microsoft's own
object files across some of the MSVC versions!).

The only recommended method is what you don't want to do -- use DLLs.
Anything else is unchartered and unsupported territory.

No. Unless someone contributes the work, it's not going to happen.

You can always cross compile from your Solaris or Intel directly for
either Cygwin or Mingw. I've posted the howto a few times to this list,
so a search should pull it up. May take a few tries, so have patience
while you're doing this the first time. Of course, this is with GCC;
you'll have to ask MS to get you a VC cross compiler (Good luck ;-).
