Since you are after increasing your program's performance, maybe you are using -fvia-c or chose an optimization level high enough that GHC decides for itself to go via C. The message is very most probably from the C compiler. You could try passing the C compiler an appropriate flag (see gcc manual) via a ghc command line option (which I am too lazy to look up).
