Environment: sun3, Sun OS 4.O.3, gcc version 1.36

#define HasGcc YES
#define HasSunOSSharedLibraries YES

When attempting to link simple Xaw programs using the sun cc complier,
referencing system X libs built as above, there are unresovled externals
which are not in gcc-gnulib. Linking with gcc is no problem.

Repeat By:

===== simple make file, test.mk ====
INCLUDES =
DEFINES =
CPPFLAGS = $(INCLUDES) $(DEFINES)

LOADLIBS = -lXaw -lXmu -lXt -lX11

xhw : xhw.o
	$(LINK.c) $(LINKOPTS) xhw.o $(LOADLIBS) -o $@
==== end of test.mk ===

	Undefined:
	_XrmDestroyDatabase
	__GetHostname
	*** Error code 1
	make: Fatal error: Command failed for target `xhw'
	(groucho) 100 % exit

Note: adding the gnu library, gcc-gnulib, to the end of LOADLIBS,
makes no difference.
