dnl Since XEmacs has configuration requirements that autoconf cannot
dnl meet, this file is an unholy marriage of custom-baked
dnl configuration code and autoconf macros.

dnl We use the m4 quoting characters [ ] (as established by the
dnl autoconf system), so quote them like this: [[foo]]

AC_PREREQ(2.12)dnl
dnl Redefine some standard autoconf macros
dnl here is how XEmacs is different:
dnl - no cache file
dnl - non-standard options
dnl - suport for extra-verbosity
dnl - ordinary libs are handled separately from X libs (might be a mistake)
dnl - various random kludges (e.g. -with-dnet=no

dnl PRINT_VAR(var var ...)  prints values of shell variables
define([PRINT_VAR],[for var in patsubst([$1],[[
]+],[ ]); do eval "echo \"$var = '\$$var'\""; done])

dnl Disable cache files:
dnl This is controversial, but I am convinced this is the right way to go,
dnl at least by default.  Otherwise there are too many surprises.

dnl If you add support for a new configuration, add code to this
dnl switch statement to recognize your configuration name and select
dnl the appropriate operating system and machine description files.

dnl You would hope that you could choose an m/*.h file pretty much
dnl based on the machine portion of the configuration name, and an s-
dnl file based on the operating system portion.  However, it turns out
dnl that each m/*.h file is pretty manufacturer-specific - for
dnl example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
dnl all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
dnl machines.  So we basically have to have a special case for each
dnl configuration name.

dnl As far as handling version numbers on operating systems is
dnl concerned, make sure things will fail in a fixable way.  If
dnl /etc/MACHINES says nothing about version numbers, be
dnl prepared to handle anything reasonably.  If version numbers
dnl matter, be sure /etc/MACHINES says something about it.

dnl Eric Raymond says we should accept strings like "sysvr4" to mean
dnl "System V Release 4"; he writes, "The old convention encouraged"
dnl "confusion between `system' and `release' levels'."
