configure set things up properly on a RedHat ELF box,

	[luke@owasso]$ uname -a
	Linux owasso.stat.umn.edu 1.2.13 #3 Thu Aug 15 06:54:53 CDT 1996 i486

The parameters it produces are

GRAPHSYS = X11WINDOWS
X11INCDIR_FLAG = -I/usr/X11R6/include
X11LIBDIR_FLAG = -L/usr/X11R6/lib

UCFLAGS = -O
ULDFLAGS =

EXTRALIBS = -lieee -ldl
EXTRAOBJS=

IEEE_FLAG=-DIEEEFP
ANSI_FLAG=-DANSI

FOREIGN_FLAG =
FOREIGN_FILE = sysvr4-foreign.h

CC = cc
LDCC = $(CC)

Dynamic loading on ELF systems is done using shared libraries. To make
the example in foo.c into a shared library, compile it with cc -c
foo.c and then do

	ld -shared -o libfoo.so foo.o

You can then use (dyn-load "libfoo.so"). You may need to use
"./libfoo.so" if the current directory isn't on your library search
path.
