* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025

My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* Check the entire length of the current argument for the EOF string with -E,Juli Mallett2005-12-311-1/+1
| | | | | | | | | | | | | | | | but don't expect a proper ASCII string to exist right here right now, don't use strcmp(3) which checks for a NUL. As we're still building the argument up, the next character might be garbage. It would probably be just as safe to temporarily write a NUL there, but if we've reached the end of argument memory that might not be the best idea, I think. It's unclear. Doing it this way seems to meet the most with the original intent. PR: 85696 Prodded by: stefanf Notes: svn path=/head/; revision=153934

* Migrate to a new way of dealing with building from old revisions ofWarner Losh2003-04-051-14/+1
| | | | | | | | | | | | | | | | | | | | FreeBSD. This method attempts to centralize all the necessary hacks or work arounds in one of two places in the tree (src/Makefile.inc1 and src/tools/build). We build a small compatibility library (libbuild.a) as well as selectively installing necessary include files. We then include this directory when building host binaries. This removes all the past release compatibilty hacks from various places in the tree. We still build on tip of stable and current. I will work with those that want to support more, although I anticipate it will just work. Many thanks to ru@, obrien@ and jhb@ for providing valuable input at various stage of implementation, as well as for working together to positively effect a change for the better.
