/* How to use:
History got us another time. If you want to write a module
that uses either native-api or os2-services...no problem.
But if you want to use both of them you run into type conflicts.
BOOL is not very surprising. But there are many other types
whose names are equal. This results from the fact that NT
should originally become OS/2 3.0.
So your solution lies in including this file instead of os2.h
and ntddk.h. What this file here does is, it puts the os2-types+
functions into the namespace OS2 while the nt-types+functions are
put into the namespace NT. The still conflicting #defines are handled
like this: If ntddk.h defintes a symbol FOO and os2.h does the same,
this file here undefines the ntddk.h-one and renames it to NT_FOO.
This is only done for conflicting symbols. Of course, this ist a
source for errors. But is there a better solution than renaming
all of the symbols?
