* 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.

| | | | | | | | | | | | | | | the child process, before executing the command. This is very useful when you do stuff like ``find ... | xargs interactive_application''. Without -o, the application would inherit the pipe as its stdin, and you thus lose any control over it. This flag has been carefully chosen to not conflit with other options of other xargs utilities like GNU xargs. Reviewed by: jmallett Notes: svn path=/head/; revision=112514

| | | | | | | | | | | | | | | | | | | | Merge xargs(1) with that of xMach. Bring in xargs(1) changes to add -L and -I as per the Single Unix Specification version 3. Proper exit status numbers are implemented, and the manual page has been updated to reflect reality. The code has been ANSIfied, and a new file has been added to xargs(1) to do the substring substitution as SUSv3 requires. Traditional behaviour should not be affected, use of -J should be deprecated in favor of the more portable -I (though -J has been left, for now).
