dnl "pkg" (typically Solaris) generally suggests package names of the form:
dnl	COMPname
dnl where:
dnl	COMP: (upper case) resembles a four character company "stock ticker";
dnl	name: (lower case) is short-form (few character) product name.
dnl
dnl It is also conventional for the name to be closely related to the
dnl installation location, typically "/opt/COMPname".
dnl
dnl See "linux-ha-dev" discussion, "heartbeat package name", from 12/Oct/2005.
dnl "LXHAhb" seems the least evil compromise for a default.
dnl Any site or packager may, of course, override this.

dnl	The GNU conventions for installation directories don't always
dnl	sit well with this software.  In particular, GNU's stated:
dnl
dnl	   '$(localstatedir)' should normally be '/usr/local/var', ...
dnl
dnl	is poor for us: much better would be somewhere under '/var'.
dnl
dnl	Here within "configure" it would be poor practice for us to interfere
dnl	with such values, irrespective of our opinion:
dnl	1. user perspective: we would have gone behind their back;
dnl	2. autoconf perspective: autoconf should avoid any OS-specific mindset.
dnl
dnl	So if localstatedir still has its default value, we issue an advisory
dnl	warning and inform folk of our own "ConfigureMe", which is ideally
dnl	suited for setting such aspects (by user, and per-OS).
dnl
dnl	[ Another option would be to detect, and to warn of, (post-expansion)
dnl	non-"/var/[...]" values: something like:
dnl		if test `expr "$localstatedir" : '^/var/.*'` -ge '5' \
dnl			-o `expr "$localstatedir" : '^/var.*'` -eq '4'

dnl ************ curses **********************
dnl A few OSes (e.g. Linux) deliver a default "ncurses" alongside "curses".
dnl Many non-Linux deliver "curses"; sites may add "ncurses".
dnl
dnl However, the source-code recommendation for both is to #include "curses.h"
dnl (i.e. "ncurses" still wants the include to be simple, no-'n', "curses.h").
dnl
dnl Andrew Beekhof (author of heartbeat code that uses this functionality)
dnl wishes "ncurses" to take precedence.  So the following ordering has
dnl been devised to implement this.
dnl
dnl Look first for the headers, then set the libraries accordingly.

dnl
AC_CHECK_HEADERS(curses.h)
AC_CHECK_HEADERS(curses/curses.h)

dnl AlanR 11 August 2001
dnl Show no mercy to broken OSes and other software.  If you have broken
dnl software, turn this feature off.

dnl NO warnings WHATSOVER will be tolerated without good reason.
dnl A distribution being broken isn't a good reason.
dnl The cure for that is fix the distribution, not destroy the integrity
dnl of the entire project by defaulting it to "off".

dnl In my experience, there are ways of making individual warnings go
dnl away.

dnl The only way I know to keep them out is to make them an absolute
dnl pain to deal with.  Otherwise they're a pain to fix.
