Log Message:
Update to 2.5. Selections from the changelog:

* The 'return' statement now actually returns, and there are now
    break & continue statements for for & while loops.

* MkDir now grists directories with 'dir', so that directory targets
    can be distinguished from other targets.

* SubDir now allows multiple overlapping roots (top level directories):
    the first SubDir of a new root uses the CWD of jam to set that
    root; subsquent SubDirs use the current SUBDIR to set the new
    root.  New FSubDirPath to compute a path (given SubDir arguments)
    and SubRules to include another root's Jamrules.  Jamrules only
    included if present; no error issued if no Jamrules file.

* $(RMDIR) has been defined for NT and defaulted to $(RM) everwhere
    else.  Not much tested.  For Michael Champigny.

* GenFile actions (on UNIX) now put . in the PATH for the execution
    of the command, so that (at least) when jam builds itself .
    does not need to be in the global path.  It is the rare case
    where a target bound in the current directory can't be used
    directly, so we fudge it by setting PATH.

* The whole /MR of Jam's name has been dropped.  It was intended
    to avoid trademark infringement of JYACC's JAM, but as far as
    we can tell (a) it wasn't enough to avoid infringement and (b)
    the trademark has lapsed anyhow.

* If header dependencies cause an object to be recompiled and the
    source file is a temporary, the temporary is now reconstructed.
    Previously, headers weren't considered when deciding when to
    reconstruct a temporary.

* -d has been reworked to make it easier to display more useful
    tracing information separate from the debugging gunk:

        -da - show all actions (formerly -d2)
        -dc - show 'causes' for rebuilding (new output)
        -dd - show dependencies (new output)
        -dm - show make graph (aka -d3)
        -dx - show executable text (formerly -d2)

    -dd is new, and more display options are anticipated.

    -n now implies -dax.

    The message "...using xxx..." now only shows up with -da.

* Several bug and portability fixes.

pkgsrc changes:
* Use the .zip distfile instead of the .tar to save space.
* Iterate with ${f} rather than ${file} to placate pkglint.
