Hi,
It appears that autoconf-2.60 may be released soon. I added comments to
longdouble.m4 and onceonly.m4 relating to the new macros in autoconf-2.59d.
I also propose a similar comment to extensions.m4, see below.

dnl empty, and the check will be inserted before the body of the AC_DEFUNed
dnl function.
+ dnl This file is only needed in autoconf <= 2.59. Newer versions of autoconf

+ dnl autoconf >= 2.60 the symbol separator is a comma, whereas here it is
+ dnl whitespace.

dnl Autoconf version 2.57 or newer is recommended.
