Fair point.  I've reflexively been using AC_PATH_PROG, but in my case 
AC_CHECK_PROG
is the better choice.

I think the autoconf documentation should encourage its users to *NOT* embed 
full pathnames
if they can avoid them, e.g., they should be encouraged to use AC_CHECK_PROG 
instead of
AC_PATH_PROG. Then spaces-in-directories would bite users (builders) less often.

It'd still be good to have a solution for spaces-in-directories.
