[Dev-C++] ANSI C++ forbids declaration 'ULONG' with no type in mapi.h

[Jorge E. E. B. <jo...@co...>]

Hello,

I'm trying to compile an application which uses the mapi.h library. I get the next error message: 
ANSI C++ forbids declaration 'ULONG' with no type.  It's on the line 133 of mapi.h
Is it a bug, or do I need to change a compiler option?

Thanks,
