I'm right now not on the machine that has the gcc3.2 compiler, but
compiling this program with gcc2.91 shows a syntax error in the line
that says "scanf .... ". Obviously, "celsius" should be "&celsius". I
wonder why the compiler on your machine didn't signal this error at
compile time. Naturally this will cause a "segmentation violation" error
at runtime. I must try this out with gcc3.2! This promises to be
interesting.
