[mod.computers.ridge] Problem with cxref

bogstad@HOPKINS-EECS-BRAVO.ARPA.UUCP (05/27/86)

PROBLEM:

	The cxref command as distributed with ROS 3.3 update 3 does
work with source files that include signal.h.

CAUSE:

	Apparently the xcpp program called by cxref(1) only allows
defined macros 8 characters in length.  The signal.h file has several
macros of the form:  #define SIGTRAPnn nn - where nn is a two digit
number.  When truncated to 8 characters, these defines conflict with
each other.

FIX:
	None is currently known.

QUERY:
	Can xccp simply be replaced with cpp?
