Thanks Brian! I did some more searching of the web and it looks like people are saying that -Wconversion may not be most useful with ISO-C code (e.g. http://gcc.gnu.org/ml/gcc/2000-06/msg00704.html). I was following, somewhat blindly, the list of "GCC warning options for numerical programs" in the GSL manual.
