- use .for loops instead of shell for loops. This means we can be
shown what is happening while it's going, rather than some pacifier
"echo" statement.
- use "${INSTALL} -C", nuke the "cmp -s" hack
- for "copies" mode, the include files are no longer touched each time
the world is built. (ie: no rm -rf. symlinks are removed, mtree builds
the new dirs or confirms the existing ones)
- osreldate.h is build in the local dir and conditionally installed,
rather than built in /usr/include and either renamed or deleted.
