When I reported this many years ago, the response[1] at the time was
"the macros are stable and intended to be usable; we're just missing
the documentation patch."

But neither I nor anyone else stepped up to actually write it.

AC_PROVIDE{_IFELSE} not documented?

[Karl Berry]

Maybe I'm going blind, but it seems that AC_PROVIDE and
AC_PROVIDE_IFELSE are not documented in the Autoconf manual. AC_PROVIDE
is mentioned but not described.  AC_PROVIDE_IFELSE is not mentioned.

$ grep -n AC_PROVIDE autoconf.texi
autoconf.texi:14935:@code{AC_DEFUN} or else contain a call to @code{AC_PROVIDE} 
to indicate
autoconf.texi:15158:@code{AC_DEFUN} or else contain a call to @code{AC_PROVIDE} 
to indicate
autoconf.texi:24975:@code{AC_PROVIDE} and ensures that macros called via 
@code{AC_REQUIRE}
