[Wine]old Wine from CVS

Be careful, there is also Wine's port.h in fst/include.
I tried copying current versions of the borrowed wine files, and cleaning
up the resulting problems (mostly just headers that need to be found in
the right place since fst's directory structure is not the same as
Wine's). It still seg faults in the same way. As you pointed out, this
wouldn't explain why the memory patch made such a big difference.
Now look in fst/libwinelib.c. This is the meat of the hack that allows
fst to use wine in the way it does. I don't think this is a "normal"
winelib application, as those shouldn't use wineserver (right?). In
libwinelib.c you will find that all kinds of things from virtual.c are
GET_SYMBOL (ntallocatevm, ntdll, "NtAllocateVirtualMemory");
GET_SYMBOL (ntfreevm, ntdll, "NtFreeVirtualMemory");
GET_SYMBOL (ntprotectvm, ntdll, "NtProtectVirtualMemory");
GET_SYMBOL (acquirepeblock, ntdll, "RtlAcquirePebLock");
GET_SYMBOL (releasepeblock, ntdll, "RtlReleasePebLock");
The change in behavior of these functions probably nukes the delicate
operation of kludging fst into wineserver.
