While I'm trying to understand what happens, I should say that a simply
workaround is to make your calculation happen in double precision (change
"3.14159" into "3.14159d0"; after all, you want a double-precision result).
g77 called sin() to perform the calculation, while gfortran calls sinf(). And
sinf() happens to be way slower than sin() (I wonder why!). Maybe a bugreport
to glibc will be in order here.
