Is there a language with lisp syntax but C semantics?

i dont buy it. you can write fft in any language. fftw for example is written in ocaml which generates c. maintainers of the package even reccomend against playing with c directly. moreover i dont see why you cant do something similar in lisp if you really wanted to
Why not use a script to generate c code instead of using macros?
