+Subject: [PATCH] Use pkg-config to detect ncurses
 
-    Update ax_with_curses.m4 to support pkg-config
-    
-    Latest version of ax_with_curses.m4 supports pkg-config. This is important
-    as libcurses is split into libcurses.so and libtinfo.so on many distros
-    and linking against libcurses.so is not sufficiant. Pkg-config allows
-    proper detection of necessary libs.

+Update ax_with_curses.m4 to latest version and use pkg-config as primary
+detection mechanism for ncurses. Latest version of ax_with_curses.m4
+supports pkg-config. This is important as libcurses is split into
+libcurses.so and libtinfo.so on many distros and linking against
+libcurses.so is not sufficiant. Pkg-config allows proper detection of
+necessary libs.

+
+Also include ax_require_defined.m4 to fix issue with undefined macro:
+
+    configure:3751: error: possibly undefined macro: AX_REQUIRE_DEFINED
+          If this token and others are legitimate, please use m4_pattern_allow.
+          See the Autoconf documentation.
+    configure:3751: error: possibly undefined macro: PKG_CHECK_EXISTS

++# SYNOPSIS
++#
++#   AX_REQUIRE_DEFINED(MACRO)
++#
++# DESCRIPTION
++#
++#   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
++#   been defined and thus are available for use.  This avoids random issues
++#   where a macro isn't expanded.  Instead the configure script emits a
++#   non-fatal:
++#
++#     ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
++#
++#   It's like AC_REQUIRE except it doesn't expand the required macro.
++#
++#   Here's an example:
++#
++#     AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])
