Ah, good.  That's what I wanted to know.  What do you say to adopting 
this style as a CVS standard:

   function( "first line\n"
             "second line\n"
             "third line\n"
             ...

with the option of breaking lines when it feels appropriate.  The syntax 
I'm trying to avoid, again, is:

   function( "first line\n\
second line\n\
third line"

I'll change HACKING if there is a consensus.

I believe the consensus was to follow GNULIB to C89 support, and GNULIB 
recently dropped K&R in favor of C89.

Incidentally, are there any other headers we check for in the call to 
AC_CHECK_HEADERS in configure.in that we can assume in C89?  stdbool.h, 
stddef.h, limits.h, float.h, and stdarg.h were already mentioned in the 
GNULIB forum.
