Some of the nested macros for reading rasters in dovplot.c cause
problems with some older C compilers. Our solution to this problem
was to upgrade to 4.3 on our Vaxen. Then the problem went away.
If you are stuck with 4.2, you can easily create temporary intermediate
variables to simplify the offending expressions. I would do this,
except I can't remember where the problems are anymore. It's only
a couple of places, though.

The Sun lint complains about "pointer alignment problems" at some
points, although I can't see anything wrong.

The Convex lint complains about my usage of sigvec and sprintf, although
again I can't find anything wrong.

SEPlib demands that at least one input file be standard in.
