GNU Autoconf test version 2.59b available

GNU Autoconf test version 2.59b is now available.
This version is numbered 2.59b because I've heard of some "2.59a"
versions floating around the net, and I wanted to distinguish it.

This is an "early beta" release.  I expect it to have several
problems, particularly porting problems on hosts other than what I use
for day-to-day development (Debian GNU/Linux 3.0r1).  It's not ready
for full scale use, but the intent is to generate the next Autoconf
release once the bugs are shaken out.

Please send bug reports to <bug-autoconf@xxxxxxx>.

Here is a list of major changes since 2.59:

** AC_CHECK_ALIGNOF
  New macro that computes the default alignment of a type.

** AC_CHECK_TOOL, AC_PATH_TOOL, AC_CHECK_TOOLS
  When cross-compiling, these macros will give a warning if the tool
  is not prefixed.  In the future, unprefixed cross tools will not
  be detected; please consult the info documentation for information
  about the reason of this change.

** AC_CHECK_TARGET_TOOL, AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOLS
  New macros that detect programs whose name is prefixed with the
  target type, if the build type and target type are different.

** AC_REQUIRE_AUX_FILE
  New trace macro that declares expected auxiliary files.

** AC_PROG_GREP
  New macro that tests for a grep program that accepts as a long a line
  as possible.

** AC_PROG_EGREP, AC_PROG_FGREP
  These macros now require AC_PROG_GREP, and try EGREP="$GREP -E" and
  FGREP="$GREP -F" respectively if possible, or else run a path search for
  a program that accepts as long a line as possible.

** AC_PROG_SED
  New macro that tests for a sed program that truncates as few characters
  as possible.
