If you want to redirect the output, the option is '-o',

ghc --make -o hithere hello.hs

(you needn't specify the extension, ghc --make -o hithere hello works too 
[or ghc --make hello -o hithere, order of command line arguments doesn't 
matter]), if no '-o' option is given, GHC defaults to the same name for the 
binary as the main module [on Windows, name.exe].
