building CALL_EXPR's with string constants

[Mike Stump]

I generally do this by writting the code in C, running emacs, and then
gdb in emacs, and then cc1 in gdb, and watch to see what cc1 does with
the code.  Then I copy it.  It'll show you the routines to call, how
to call them, what you need to check for, and so on...  If you just
ask it.  It usually gives pretty good advice.
