< --------------------------->


While trying to compile the MicroEMACS 3.7 sources with the Manx 3.20a
compiler, I ran into a problem with the #if'd code used to select
machine/compiler/os environment.

Problem:
	Error #109's to say that the if values need to be integer
	constants, but only if I compile with 32 bit ints. Compilation with
	16 bit ints works as expected.

To reproduce:
	Compile the program below with

		cc foo.c

	This works, while

		cc +l foo.c

	fails.

Questions:
	1. Has anyone else seen this behavior?
	2. Has anyone found a work around?
	3. Does the 3.30 compiler do the same thing?

Thanks,
