null) if toplevel/config/mh-{host} doesn't define it. Fixes a
problem with autoconf trying to configure on a host without GCC.
* config.sub: Add `magic' as an OS target for General Magic.
only use generic MPW Makefile sed if present, edit a file
named "hacked_Makefile.in" instead of "Makefile.in" if present.
* mpw-README: Add problem notes about CW6 and CW7.
sub-directory Makefiles, instead of using DISTSTUFFDIRS and
DISTDOCDIRS.
(DISTSTUFFDIRS, DISTDOCDIRS): Removed - no longer used.
(newlib.tar.gz): Don't pass DISTDOCDIRS to recursive make.
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.
(CONFIGURE_TARGET_MODULES): New variable.
($(DO_X)): Loop over TARGET_CONFIGDIRS as well as SUBDIRS.
($(CONFIGURE_TARGET_MODULES)): New target.
(configure-libg++, configure-libio): New targets.
(all-libg++): Depend upon configure-libg++.
(all-libio): Depend upon configure-libio.
(configure-libgloss, all-libgloss): New targets.
(configure-libstdc++): New target.
(all-libstdc++): Depend upon configure-libstdc++.
(configure-librx, all-librx): New targets.
(configure-newlib): New target.
(all-newlib): Depend upon configure-newlib
(configure-xiberty): New target.
(all-xiberty): Depend upon configure-xiberty.
* mpw-configure: New option --cc to select compiler to use,
paste options set according to --cc into the generated
Makefile, generate the Makefile by sed'ing the Unix Makefile.in
if mpw-make.sed is present.
* mpw-config.in: Don't test for gC1, test for mpw-touch,
add forward includes for PowerPC include files.
* mpw-build.in: Build using Makefile.PPC if present.
(do-byacc, etc): Remove separate version resource builds.
(do-gas): Build "stamps" before "all".
(do-gcc): Build "stamps-h" and "stamps-c" before "all".
* mpw-README: Update to reflect --cc option, PowerMac support,
and recently-reported compatibility problems.
