I recently purchased C/80 V3.1.  The library seems very complete, and
*C* sources are included.  The most significant limitations to V3.1
include:

	Float, double, entry and typedef keywords not implemented
	Float and long constants and arithmetic (Float and long may be
		added with the optional [$29.95??] "mathpak")
	Typedef not implemented
	Bit fields not implemented
	#line directive not implemented

    **  Function calls must have the same number of arguments as the
		called function definition.  (There is a hack to make
		[s]printf work correctly.)
	#define does not allow arguments
	Blocks: declarations are allowed only at the beginning of a
		function

For $49.95, I've found C/80 V3.1 to be a very useful tool.  My biggest
complaint is inherent in the nature of it's recursive descent
algorithm; once an error is discovered, the compiler "discovers" MANY
more errors until it gets itself resynched with the input.
