I found that when I try to include functions defined in ISO C99 from math.h,
g++ throws an error when compiling the program. It specifically complains
about two lines in math.h, which when changed a litte don't produce the errors
anymore. I have glibc-devel-2.2.4-19.3 installed. The diff output for the
change is at the end of my email. If this is not the right forum for this kind
of problem and somebody knows a better place for this, please let me know.
Thanks, nick
