Remove the numbered source and patches and automatically manage
sources and patches. This removes the overhead in maintaining large
collections of patches.
On NetBSD with ksh changing into a symlink made PWD the link's
target path so a 'cd ..' returned you to that parent and not
the parent you started from. Record the build top and then
change back to that path.
Change the package names to the actual packages and remove the
extra directory in the build tree. This makes the paths simpler.
Set up the rules to manage the separate host and build setting to
allow a Canadian cross to complete.
Update the scripts to move the build directory and host/build
flags into the defaults so they are common for all build
configurations.
Add support to build MinGW tools using Cygwin. This is a Canadian cross
build.
Do not expand the directives when parsing a configuration file. Hold
in the package object the text as read from the configuration file. Still
parse the logic but leave the macros. This allows a configuration to be
varied when the build happens. The Canadian cross uses this to build a
build compiler used to build a Cxc runtime.
Add Cxc support to the build module. In the defaults add rm and rmfile
macros, add Cxc paths and pre-build script code.
In the setbuilder check for a Cxc build and if so and the package
allow Cxc build the build host version then the host target
version.
Add cygiwn support to the defaults processing and to the Windows module.
