I just tried compiling the emacs22 package from unstable with gcc 4.3,
and ran into an issue similar to what Martin described back in
May 2007 for another package in #425544, with the following differences:
- it's not an infinite loop but a one minute hang
(see the alarm() in conftest.c)
- the build therefore proceeds, but emacs wrongly assumes there's no
working system mktime()
- Martin said it's "a bug in older versions of autoconf", but as far
as I can see these older versions include the latest upstream
version and also the Debian package in unstable
For increased fun, fixing autoconf won't automatically fix all current
and future packages using AC_FUNC_MKTIME (upstream might use an
unfixed autoconf version).
It could be harmless (except for a few one minute pauses the emacs build
seems to work fine, and emacs has some replacement function), but
someone might want to check how many packages in Debian use
AC_FUNC_MKTIME and whether some of them might have real problems.
