Hash :ab9ef6cf Message :Sync ChannelDefs.pm from autoconf.
ChannelDefs.pm *ought* to be kept in sync between automake and autoconf,
because it defines the set of valid -W options, and autoreconf assumes
that it can pass arbitrary -W options to all of the tools it invokes.
However, it isn’t covered by either project’s ‘make fetch’ and it hasn’t
actually *been* in sync for more than 17 years.
This patch manually brings over all of the changes made on the autoconf side.
Most importantly, there is a new warnings channel ‘cross’, for warnings
related to cross-compilation. Also, the ‘usage’ function now *returns*
the text to be put into a usage message, instead of printing it itself.
(This is necessary on autoconf’s side.)
* lib/Automake/ChannelDefs.pm: Sync from autoconf.
(cross): New warnings channel.
(portability-recursive): Document.
(usage): Now returns the text to be printed, instead of printing it.
(parse_warnings): Second argument may now be a list.
