If you don't feel like modifying all of your Makefiles to change the 
compiler flags, you should be able to edit /etc/xlc.cfg and set them
once and for all.  

That's one *really* nice thing about the RIOS C compiler -- all of the 
default options are set through this file, and you can have different 
option sets depending on the name by which you invoke the compiler.  
(For instance, cc and xlc are really the same binary, but with different 
options controlled by /etc/xlc.cfg)

When porting code from non-ANSI environments, I found it helpful to
set the options for "cc" so they include -qchars=signed and -qnoro.
