I would check the instructions for creating DLLs... I myself haven't
done that "manually" for years but I remember that being something
weird, not like creating usual Win32 executables. Creating Win32s
executables maybe could be compared to creating DLLs, that was a 2-phase 
process because of those required "relocations", the functions
needed being relocatable in the address space, not "linear"...
