There's the -ansi flag.  However, as the GCC man page says:

   The macro "__STRICT_ANSI__" is predefined when the -ansi option is
   used.  Some header files may notice this macro and refrain from
   declaring certain functions or defining certain macros that the ISO
   standard doesn't call for; this is to avoid interfering with any
   programs that might use these names for other things.

That *might*, on some platforms, cause functions that Ethereal requires 
not to be declared or cause macros that Ethereal requires not to be 
defined.  I don't remember whether we've ever tried compiling with 
-ansi.  I'll see what happens if I try that on OS X 10.3.7, at least - 
some other OSes might use __STRICT_ANSI__ in ways that OS X doesn't, so 
even if it works on OS X it might not work on other platforms.
