odd sqrt problem

[blackdragon]

im encountering an odd problem with sqrt; i use glibc 2.1.3, as included
with slackware 7.1

the following code will not compile due to an "undefined reference" to
srt:
---snip
#include <math.h>
main() {
    double x;
    double y = 16.0;
    x = sqrt(y); }
---snip

i get odd little notes about object files in /tmp

im not on the mailing list so please reply to address@hidden if
you think you could help me out

i can provide just about any other information you might require to help
me solve this problem -- if you are so willing :)
