I go through the Makefiles (or the one(s) relevant to the code I'm 
working on, anyway) and remove -O2 from CFLAGS and CPPFLAGS.  If there's 
a neater way, I didn't find it after a brief look.
Incidentally, is this a bug or deficiency in the make process?  CFLAGS 
contains everything included in CPPFLAGS (CPPFLAGS duplicates values in 
CFLAGS), so CPPFLAGS would seem to be redundant.  I haven't been able to 
determine the official purpose of CPPFLAGS after a fairly extensive 
search, and the best I've come up with is that the default value is null 
and the rest is "convention".  I suggest the value in Ethereal for 
CPPFLAGS should be null.
