+ From fnf@ninemoons.com (Fred Fish).

* Test release 2.10.1.
(AC_CHECK_LIB, AC_CHECK_HEADER, AC_CHECK_HEADERS): Replace use of
tr with sed, to avoid a bug in the AIX 4.1.3.0 tr reported by
Alain KNAFF <Alain.Knaff@imag.fr>. He says that version of
- tr interprets \055 magically like an unquoted -.
+ tr interprets \055 as a range specifier, like an unquoted -.
* acspecific.m4 (AC_PROG_MAKE_SET, AC_CHECK_HEADER_DIRENT,
AC_CHECK_HEADERS_DIRENT): Ditto.
Use AC_CHECK_FUNC in the system-dependent libs tests.
From Larry Schwimmer <rosebud@cyclone.stanford.edu>.
Wart removal: Don't require AC_ISC_POSIX.

+ Don't blather about being called before AC_TRY_LINK,
which is now called in AC_PROG_CC. Don't encourage using this macro.
* acconfig.h (X_DISPLAY_MISSING): Add entry.
* acspecific.m4 (AC_PROG_CXX): Check for cc++ for NexT.
From Carl Edman <cedman@princeton.edu>.
- (AC_ISC_POSIX): Require AC_PROG_CC, since it uses $GCC.
- From gvran@uddeborg.pp.se.
(AC_PROG_CC, AC_PROG_CXX): Check whether -g works even if
C[XX]FLAGS is set. From T.E.Dickey <dickey@clark.net>
(AC_FUNC_FNMATCH): New macro.
(AC_CACHE_WRITE): Set the cache values only if not already set.
(AC_PARSEARGS, AC_OUTPUT): Allow giving an empty prefix or exec_prefix.
- AC_CONFIG_AUXDIR*.

* acgeneral.m4, acspecific.m4: Rename AC_CONFIG_AUX* to
