making sure the copies in the object tree are writable. When files in the source tree are not writable (as would be the case for a p4 tree) then a buildworld -DNOCLEAN will try to copy over the existing non-writable headers. This fails. Instead we cat the headers with redirection. This is just one of the possibilities.
This subtree is world-exportable, as it does not contain any cryptographic code. At the time of writing, it did not even contain source code, only Makefiles and headers. Please maintain this "exportable" status quo. Thanks! MarkM markm@freebsd.org 20th Sept 1997
