them, based on either an existing Makefile or on searching for gcc
in PATH. Substitute for CC and CXX in Makefile.
* configure.in: Remove libm from target_libs. Separate
target_configdirs from configdirs. If CC is not set in
environment, try to get it from a host Makefile fragment. Rewrite
changes of configdirs to use skipdirs instead. A few minor
tweaks. Take directories out of target_configdirs as they are
taken out of configdirs. Remove existing Makefile files from
subdirectories. Substitute for TARGET_CONFIGDIRS and
CONFIG_ARGUMENTS in Makefile.
* Makefile.in (TARGET_CONFIGDIRS): New variable, automatically set
by configure.in.
(CONFIG_ARGUMENTS): Likewise.

case where a directory has a configure.in file but no Makefile.in
more gracefully (with an actual understandable error message, even);
add support for --without (and add this to the usage message); also
explicitly add a --host=${host_alias} to the command line when
config.guess is used
screws nested configures. "unset PWD" is the right answer, except that
Decstation sh doesn't *have* unset.
Note also that the send-pr build will fail if you have PWD in your
environment, because emacs also (foolishly) trusts it.
* configure: just set PWD=`pwd` at the top, since Ultrix sh
doesn't have unset and all success paths (and most error paths)
out set it anyway. (Note: should change all uses of ${PWD=`pwd`}
to just ${PWD} to avoid confusion.)

* configure: always set $(tooldir) to $(libdir)/$(target_alias),
even for a native compilation.
makefiles depend on config.status to tell if a directory has been
reconfigured for a different host. This change prevents those
directories from remaking everything in the case where the reconfig
was only intended to rebuild a Makefile.
like 'configdirs', except that configure doesn't re-invoke
itself for subdirs, it just creates a Makefile for each subdir.
* configure.texi: Document subdirs.
