Quote AC_DEFUN macro names

[Alexandre Duret-Lutz]

Hi!

I'd like to suggest this patch for branch-1-4.  

These days I'm running a hacked version of aclocal to detect
unquoted macro names in AC_DEFUNitions.  These are know to cause
trouble when someone attempts to redefine them.  (And in the
future, when Autoconf provides an aclocal replacement, it might
be the case that several definitions of the same macro are
temporarily accessible at the same time -- in which case they'd
better be quoted!)
