I have better patch which extends detection mechanism, so that along with size/mtime checksum of the compiler binary is stored as well. Since compiler binary linked from the same sources/objects will have the same checksum it allows ccache to be used safely with buildworld. Do you have any interest in putting it into the port?
most definitely. I'm all for saving a few min. in compile time. Michael

CCACHE_NOHASH_SIZE_MTIMEThis tells ccache to not hash the real compiler's size and modi- fication time. Normally this is the mechanism to detect compiler upgrades. There are situations however, where even though the compiler's size or modification time has changed you can safely use the cached objects (e.g. if as part of your build system the compiler is built as well and the compiler's source has not changed; or if the compiler has only changes that do not affect code generation). Use this feature only if you know what you aredoing.
