Attached are patches to the current release of xgraph to port it to
Linux. It think they'll be useful elsewhere to (probably at least
with *BSD), they generally seem to improve Posix-ness.
Also derivative.* was missing from the Imakefile
Also, the current xgraph dies on the surface{,2}.xg sample data sets
for me. Here's the traceback:
(gdb) run examples/surface.xg
Starting program: /usr/src/MISC/xgraph/xgraph examples/surface.xg
warning: Unable to find dynamic linker breakpoint function.
warning: GDB will be unable to debug shared library initializers
warning: and track explicitly loaded dynamic code.
Program received signal SIGSEGV, Segmentation fault.

$1 = (PointList *) 0x806e700
(gdb) p D1List
$2 = (PointList *) 0x82445d8
(gdb) p D2List

Finally, if you want I can send you a Linux ELF binary.
