Thanks.  It will have to wait until the weekend to be committed.  I am 
off on a trip in a few minutes.  I lost all the available time this 
morning to an embarrassing problem with SECNDS with 4.0.  I hade missed 
the fact that there in an internal_free as well as free_mem.  For 
mainline this does not matter but it causes a segfault with the old 
version of the library.  I will tidy up mainline when I commit this 
patch that you have okayed.

It's a small start anyway.  I have a patch for PR23912 that I will 
submit at the weekend and a prototype implementation for %VAL.

Cheers
