It is unlikely that the sqrt is in gcc, but it could be in a library that
comes with gcc. Try to find where these are, and use an environment
variables to change the linking as in :
setenv LDFLAGS "-L/directory -lm"
if directory is your gcc library-directory and libm.a (or libm.so) is the
math library.
