I know very little about developing C on the Macintosh. I used Think C
two or three years ago to do a small project, and have used MPW a little
bit to assemble MCL's kernel, but that is the extent of my experience.
From looking at the November, 1992 APDA catalog, I would guess that you would
need to get the MPW C Bundle, which was listed for $425. The description of
the MPW C compiler version 3.2.4 says "The MPW C compiler supports K&R C,
as well as many ANSI extensions to C, including function prototypes and strong type checking. It includes a standard C library that offers the functions
described in the ANSI C standard." I do not know if "many ANSI extensions"
means that it will have problems with your "ANSI C", nor do I know if
Think C is closer to the ANSI standard (or if that will matter for your
code), or how the effort involved in building Think C stubs using Guillaume
Cartier's package compares to writing DEFFCFUN stubs to interface to MPW C.
Can someone else help out?
