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

### You would hope that you could choose an m/*.h file pretty much
### based on the machine portion of the configuration name, and an s-
### file based on the operating system portion.  However, it turns out
### that each m/*.h file is pretty manufacturer-specific - for
### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
### machines.  So we basically have to have a special case for each
### configuration name.
###
### As far as handling version numbers on operating systems is
### concerned, make sure things will fail in a fixable way.  If
### /etc/MACHINES doesn't say anything about version numbers, be
### prepared to handle anything reasonably.  If version numbers
### matter, be sure /etc/MACHINES says something about it.
###
### Eric Raymond says we should accept strings like "sysvr4" to mean
### "System V Release 4"; he writes, "The old convention encouraged
### confusion between `system' and `release' levels'."

dnl If found, this defines HAVE_LIBDNET, which m/pmax.h checks,
dnl and also adds -ldnet to LIBS, which Autoconf uses for checks.
AC_CHECK_LIB(dnet, dnet_ntoa)
dnl This causes -lresolv to get used in subsequent tests,
dnl which causes failures on some systems such as HPUX 9.
dnl AC_CHECK_LIB(resolv, gethostbyname)

dnl FIXME replace main with a function we actually want from this library.
