Ack! The problem is that those warning numbers change from one SGI C/C++ compiler
to the next. This code might turn off the 'const' message now - but next time
it might turn off the 'unused variable' warning or something else that you should
really care about.

Can't you use a 'cast' to fix it? (I don't use C so I don't know for sure):

   pfPostMultMat(m2,(const float (*)[4]) m3);
