William, how much work would it be for a good student programmer to
rewrite sympow in a way which would make everyone happy? I expect that
Mark would cooperate even though he does not seem to want to do this
himself. Sympow is in several separate files so the task could be split
up. One possibilty might be to ask the pari developers if they might be
interested in converting it to be part of the pari library.

... where the return value of malloc() isn't checked either.
