Explanation: This section is a merge of the current Cygwin patches to libtool.m4,
	plus a couple of changes with respect to MinGW

Hunk 1:	The comment says it all

Hunk 2:	Apparently a bugfix to Cygwin's postinstall_cmds. I want to borrow those
	postinstall_cmds later, so we should have the latest version.

Hunk 3:	Up to the '-' came from Cygwin. The next bit of the comment is mine. I'm
	not even sure if $ltdll_cmds work any more. I've bee using the $NM
	incantation, since I do have a sort and a uniq.
