One of the : things it is telling me to do is to enable prototype checking with my : compiler. I am using djgpp. (1) is it actually necessary to turn on proto- : type checking with gcc? and (2) what is the command-line extension to do so? If you define a prototype and include it, gcc will spit at you if the types are wrong, without prompting. If you want it to spit at you for not including prototypes, or just like having your every mistake highlighted, use the -Wall flag to turn on all except a few esoteric warnings. Compiler parameters are discussed in the online info browser that came with djgpp (if you downloaded it). Hope this helps, Jon.
