I think there are some threads further down talking about namespaces and the
STL (the STL provides generic templates for min/max which work with any
comparable types).  I of course neglected to read these suggestions before
I compiled and took a more brute-force approach by changing all calls to
min/max to fmin/fmax (and you also have to change min3 and max3).  Not sure
if fmin/fmax will be available on IRIX though.

Thanks for the help.
