Thank you for taking the time to explore all of this - I'm not a Windows
user so all the Windows-related stuff in PCRE is what other users have
contributed over the years.

I'm afraid you are too late for the 8.33 release, which is currently in
testing. I am hoping to get it released next week, and I think your
patch is too large to put in at the last minute.

However, there will no doubt be an 8.34 in future. Once 8.33 has settled
down (that is, after a few weeks when nobody is shouting about any
disasters in it), I will look at your patches.

[Incidentally, the malloc/free static pointers are probably the worst
part of my naive 1997 design that still survives. The pointers should
really be passed in in some kind of "context" data structure which would
be thread-safe. However, changing this implies a whole new API for PCRE,
and although I have some ideas, I am not very keen on starting any major
PCRE projects nowadays.]
