This really begs a question.  Should we put a bomb under utils.c 
breaking it up into smaller chunks (gdb/utils/*.c) so that people can be 
more confident about this.

At present utils.c contains so much that someone trying to change it is 
never really sure what the consequences of an include file tweek are.
