I'm using Borland C++ 4.5 to develop a 16 bit MAPI application.
I downloaded MS SDK with examples and I got problems
with a very simple MAPI client example written in C.
I got the error (preprocessor error message):

***error 8-byte packing is not supported!!***

that is a message put in PSHPACK8.H...
...
#elif defined(__BORLANDC__) && !defined(__FLAT__)
    #error 8-byte packing is not supported!!
...
does it mean that I can get compile sucess for 32 bit only ???

Thanks in advance,

Davide Sanna
