[Bug-gnubg] New win builds on gnubg.org (20090915 code)

[Massimiliano Maini]

I've added the choice between SSE2 (default) and non-SSE executables.
If SSE2 is selected, a test is run and if SSE2 is not supported, a
pop-up tells the user to re-run the install selecting non-SSE exes.

Michael D. (or anybody else with non-SSE2 CPU) can you test it ?

1- run the installer on your recent PC, select SSE2 exes, and then
check that the installed exes are SSE2 (run gnubg, Help/About gnubg
menu, Build Info button, you should find "SSE/SSE2" supported amongst
the features).

2- run the installer on your old PC, select SSE2 exes, and a pop up
should appear warning you. Then re-run the installer and select
non-SSE exes and then check that the installed exes are non-SSE2 (run
gnubg, Help/About gnubg menu, Build Info button, you should *not* find
"SSE/SSE2" supported amongst the features).

MaX.

P.S.
Next time I'll add the check the other way round too: you select
non-SSE exes on a SSE2 PC, you get a warning too.
