You've put this in the section guarded by NO_SHLWAPI_STREAM, but in the 
PSDK header it isn't guarded by this define. If it were the case, then 
you could have fixed the issue in files that include shlwapi.h by 
defining this before including it.

However, I think having to work around not being able to use the 
IStream_Read and IStream_Write macros is a bit ugly.
