       G++ is generating HUGE executable files for source code that is only
   five or six lines long on the CS computers at my school
   (pegasus.cs.tulane.edu). A program called "strip" seems to reduce the
   problem to about 180K, but thats still a gross waste of space. Are the
   CS administrators correct in saying nothing more can be done to
   alleviate the problem? I believe they are running a recent ver of IBM
   AIX, if thats any help. I cannot write serious programs if they turn
   out so wastefully big, so please help. email and post please.

Check out which libraries does it include to your program, and when
necessary, replace the libraries with your own versions of the
library. Also there's usually startupcode which parses argc and argv
and initializes stack included. Those are the only things you can
take from the file size. Tho, removing either of those will disable
some of the features standard C offers, like displaying text or
opening files. (These are for any compiler, and i'm not saying this
is possible or feasible in g++)
But trying to figure out what's in those 180kb will help for sure.
