There doesn't seem to be anything wrong with the source code.  When
compiling with maths functions, make sure you use -lm to actually link in
the library... but that should give an error more like:

bash-2.02$ gcc -o testpow testpow.c 
Undefined                       first referenced
 symbol                             in file
pow                                 /var/tmp/cca000JP1.o
ld: fatal: Symbol referencing errors. No output written to testpow
bash-2.02$ _

As to your error, I'd be checking the actual header file which is being
included, ie /usr/include/math.h.

Try gcc -E testpow.c | less, to see exactly what's being included.

(what?  I'm the first one in on -C- question??)
