release update

[Ralf Wildenhues]

Here's another round-up of issues; not including patches with stuff we
get from Automake, or have already agreed on to postpone, or stuff I
have forgotten about now (pointers appreciated).


- stdbool issue (Bruno)
http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00027.html
Needs review.

- proposed AC_PROG_MKDIR_P
http://lists.gnu.org/archive/html/bug-autoconf/2006-04/msg00041.html
Is anyone working on this?

- weird autom4te failure on MinGW
http://lists.gnu.org/archive/html/bug-autoconf/2006-04/msg00073.html
I cannot reproduce this on my MinGW system.

- Interix failures
http://lists.gnu.org/archive/html/autoconf/2006-05/msg00022.html
Propose to ignore unless we get more feedback.

- some way to warn about exit(3) in tests?
http://lists.gnu.org/archive/html/autoconf/2006-04/msg00141.html
Proposed approaches are either expensive or not very precise, or both.

- datarootdir
http://lists.gnu.org/archive/html/autoconf/2006-04/msg00073.html
There are still cases we don't warn about.  (AFAIK Stepan is working
on a patch to warn in that case.)


I'd like to get 2.60 out in May, if possible.  Ideally a week after and
unchanged from a previous beta release.  OK?

Cheers,
Ralf
