I'm trying to make xgdb from the 2.7 sources distributed with Emacs
18.53 on a Vax running Ultrix 3.0 with the MIT X11R3 libraries.

It appears that something is wrong with the Makefile.  Here's the end
of the output:

cc  -o xgdb main.o firstfile.o blockframe.o breakpoint.o findvar.o stack.o source.o  values.o eval.o valops.o valarith.o valprint.o printcmd.o  symtab.o symmisc.o coffread.o dbxread.o infcmd.o infrun.o remote.o core.o inflow.o xgdb.o lastfile.o command.o utils.o expread.o expprint.o pinsn.o  environ.o version.o  -lXaw -lXt -lX11 obstack.o
