        The problem probably lies with the 'log' function.  By including
math.h, and compiling with the -lm option (that is, if you actually want
to use the mathematical functions), you are including a definition for log
which already exists (log as in math, and log as in syslog).  A long time
ago, I renamed the circlemud 'log' function on my system with a sed/awk
script. There are other solutions, but at the time, this was the easiest.
