To get gcc to act as a strictly conforming ANSI C compiler, invoke it as:
gcc -ansi -pedantic-errors
My personal favorite is:
gcc -ansi -pedantic-errors -O -g -Wall
The combination of -O and -Wall will produce some very interesting warnings:
* variable used before initialized
* variable not used at all
* implicitly declared function (i.e. you forgot <stdio.h> or some such)
* pointer abuse
