* Jamfile Caching
As large build systems may consist of a huge number of Jamfiles, the
mere reading of these files may take considerable time. This version
implements a cache for them. Since the time stamps of the files still
need to retrieved to check whether the cached entries are still up to
date, the benefits to be expected are not that big though.
The name of the cache file is controlled by the JCACHEFILE Jam variable.
If JCACHEFILE is left unset (the default), reading and writing of a cache
file is not performed. Setting the SEARCH and LOCATE variables does work
as expected.
* Bug Fixes
- Removed superfluous search() in compile_on() (compile.c), which slowed
down on target rule invocations.
