More RISCy Business re: VC_EXTRALEAN


Caution: there are differences in MSVC's behavior when #defining 
VC_EXTRALEAN (as stdafx.h tends to do) on RISC platforms vs Intel.
The difference I just ran into is that the RISC implementation excludes
Win32 tape API functions and definitions, whereas the Intel version does
not.  If you are calling tape API functions and your project has
generated an stdafx.h file, make sure to comment out the #define
VC_EXTRALEAN line at the top (on the RISC build).

Who knows what other differences exist between these implementations?
