math.h doesn't include pow?

[Vince Sabio]

My C library documentation states that the "pow" (power) function is 
included in math.h. However, when I go to link (compiling and linking 
with gcc), I get the following:

In function `[function name]':
[path/]datetime.c:668: undefined reference to `pow'

Yes, I'm including <math.h>. If I compile the exact same code under 
Darwin (BSD on PowerPC), it compiles fine. It also compiles in 
CodeWarrior. Is anyone else familiar with this problem? Could I have 
a path set up incorrectly, and be using the wrong libraries?

Running FreeBSD v5.1, installed from CD, including the developer 
tools. Single-boot system; there is no Microsoft software anywhere on 
the machine, so it's not their fault (for a change). ;-)
