TNT version 1.2.6
Downloaded from http://math.nist.gov/tnt/index.html
Modified to convert from namespace std C header files
to standard C header files, ie, eg, from <cmath> to <math.h>
because some old compilers still exist.
In particular, on SGI IRIX the new form is supported with
MIPSpro 7.4 C++ and IRIX 6.5.18 (m/f) or later:

But many institutions still have, eg, MIPSpro Compilers: Version 7.3.1.2m
