NOTE: You may need to set the path for executables for the Mac platforms in the IDE by hand (m68k shown in screenshot, powerpc similar, but with "mppc"). The installer seems to register include and lib directories, but not executables!

For command line builds:

set path=c:\msdev\mac\bin;c:\msdev\mac\m68k\bin;%path%
set include=c:\msdev\mac\include;%include%
set lib=c:\msdev\mac\m68k\lib;%lib%

-or-

set path=c:\msdev\mac\bin;c:\msdev\mac\mppc\bin;%path%
set include=c:\msdev\mac\include;%include%
set lib=c:\msdev\mac\mppc\lib;%lib%
