It had symbols.

DOH!

gcc-3.1.1 (or maybe gcc-mingw-3_1-20020516-1) clobbered my old 
gcc-2.95.3 (mingw) version of /usr/lib/mingw/libstdc++.a.

I copied it to libstdc++-2.a AFTER installing gcc-3.1.1.  After 
restoring my original file (to libstdc++-2.a), everything worked.

Sorry for the confusion (boy, I feel silly).

So,

3.1.1:

gcc works
gcc -mno-cygwin works
g++ works
g++ -mno-cygwin works
g77 works
g77 -mno-cygwin works

2.95.3-8:

gcc-2 works
gcc-2 -mno-cygwin works

g++-2 works
g++-2 -mno-cygwin works (provided one installs libstdc++.a from mingw's 
gcc as /usr/lib/mingw/libstdc++-2.a)

g77-2 breaks:
  /usr/lib/libcygwin.a(libcmain.o)(.text+0x81): undefined reference to 
`WinMain AT 16'
g77-2 -mno-cygwin breaks:
  /usr/lib/mingw/libmingw32.a(main.o)(.text+0x8d):main.c: undefined 
reference to `WinMain AT 16'

I gather you figured out what was "wrong" with g77-2 in gcc2-2.95.3-8 ?

P.S. Now, my tests are very very simple.  Consider them "basic" 
functionality tests.  We still need more "real world" testing before 
these are ready to go, IMO.

Also, I'm thinking that the files in
   /usr/include/g++-3/ (including _G_config.h)
should go into a
   gcc2-mingw-2.95_YYYYMMDD-X
package (perhaps along with

usr/lib/mingw/libg2c.a
usr/lib/mingw/libgcc.a
usr/lib/mingw/libobjc.a
usr/lib/mingw/libstdc++.a from mingw's gcc, appropriately '-2' renamed)

Hey, wait a minute -- maybe that's why g77-2 is failing?  It's linking 
against libg2c.a from 3.1?  Yep, seems so!
