Wine patch

[Bob Goodwin]

Below is a `diff -c' of the fix I generated for a bug I reported (#249.)
The bug causes a stack overflow during a `_wine_call_from_16_regs'. The
patch adds a mask to clean the upper half of the ESP register after
setting the esp using a word sized lssp. I have compiled and tested this
patch and it works (no more stack overflow.) This patches
wine-xxxx/tools/winebuild/relay.c which is used to generate the code for
wine-xxxx/if1632/asmrelay.s.
I have never submitted a patch before so if this one is not workable for
some reason please let me know.
