Because the linker and the preprocessor are independent programs involved in
the compile process. #include causes the compiler to know about the
prototypes (arguments and return type) of a function like sqrt(). -lm tells
the linker to actually link against the library libm.so which actually
implements the sqrt() function.

I'd be interested to hear from him. There are so many pseudos around taking
his name in vain.
