On Debian/testing(sarge), 5.0.3rc3:

- If I compile with gcc-2.95 (and the -lpthread fix) it works.

- If I compile with gcc-2.95 (without -lpthread) it gets past the point
of the SegFault, but hangs after "Adding panels". [same as gcc-3.3
without the -lpthread fix]

- If I compile with gcc-3.2.2 on Redhat 9 it SegFaults after "building
color table".

- If I compile with gcc-3.3 (with or without the -lpthread fix) it
SegFaults after "building color table".


I've got gcc-3.0 and gcc-3.2.3 installed too, so I'll see if I can
narrow down that end some more.


might newer gcc's not like ""?
   map = G_find_file2 ("cell", filename, "");
