Cross-reference files for C programs.

[utzoo!decvax!duke!unc!reh]

	Any description of current programs to produce cross-reference
files for C programs would be welcome.
	We are developping an option to the C compiler to produce an
extensive cross-reference file.
	The only related C programs about which we know are UNIX's Adb,
UNIX's Sdb, and a program that simply produces a list of variables with
their source code line numbers.
	Please send any suggestions to:
		duke!unc!reh	or	reh.unc at udel-relay   .
	Thanks.
