Re: [RFC] Update to current automake/autoconf/libtool versions.

I don't understand this:

isn't it independant of the switch?
It's a result of using the ylwrap from autoconf-1.7, which is needed since the rules for the binutils/ parsers are automatically generated by automake.

Same with this?

+ AC_DEFINE([HAVE_LONG_DOUBLE], [], [Define if the `long double' type works])

(or did the new autoconf change the interface causing a warning if the three parameters were not present?).
Not even a warning: it blows out autoheader with an error. The new AC_DEFINE interface deprecates the use of a template file, and instead requires all the information to be provided by the AC_DEFINE commands (it's particularly annoying since the warning about the existence of a template file is about 10 lines long, ALL CAPS, and can't be turned off with --warnings=none).

I actually made a point of not fixing any warnings during the conversion that weren't symptoms of real errors. My reasoning is that once the flag day part of the conversion is done, we can fix the warnings in individual directories individually, but that for the initial conversion it was best to keep it as simple as possible.
