Guido van Rossum 739267b7c3 Completed (hopefully) the unification of THINK 6.0 and MPW 3.2
versions -- they now share config.c and config.h, and statting is
always done through macstat.[ch] (THINK's <stat.h> defines funny
constants).  Also the configuration of stdwin is done differently: you
have to define USE_STDWIN to the compiler prefix.
