If you can't use -Wall you might try lint. There is a lint package
called "lclint". "lint noproto.c" (your example code) produces this:
LCLint 2.4b --- 18 Apr 98
noproto.c: (in function main)
noproto.c:5:1: Assignment of double to float: x = atof("123.456")
Types are incompatible. (-type will suppress message)
noproto.c:3:14: Parameter argc not used
A function parameter is not used in the body of the function. If the
argument
is needed for type compatibility or future plans, use /[EMAIL PROTECTED]@*/
in the
argument declaration. (-paramuse will suppress message)
noproto.c:3:27: Parameter argv not used
Finished LCLint checking --- 3 code errors found
