Ooops, I'm sorry. This is plain wrong. Wine wouldn't be able to
handle them regardless of MAP_FIXED in that case. 

The problem occurs, for example, if there's a file (which may be
a DLL or a data) was mmapped at 0x800000 and Wine attempted to mmap
a stripped DLL that has 0x800000 or so as ImageBase with MAP_FIXED. 
New mapping would zap the previous one and this would lead to crash.
