I believe the person you are referencing is Blair McIntyre.  Last time I communicated with him he was a professor at Georgia Tech.

Oh I should be clear on what I mean, exactly, when I say things like that.

Pickles "version 1", what was in SRC M3 and is in PM3, were never from what
I understand completely implemented?  For one thing, they didn't support
endian-switching.

A gentleman with a Scottish name that eludes me at the moment came
out with "Pickles version 2", which do the endianness-switching, among 
other things.

My "PM3" includes a lot of things from newer M3s, such as this Pickles version 2.

I really am not enamored with my ancient PM3.  I just need something
that works reliably on Cygwin *and* FreeBSD (which it does).  So adding
the odd CM3 library to it is no big deal.

But the TEXT issue is so deeply embedded in the compiler and runtime
that I haven't had the guts to try to retrofit CM3 TEXTs to PM3 or
vice versa.

I am almost certain I have tested interchanging pickles between my PM3 code
and some CM3 code and verified that it did work as long as there were no
TEXTs involved.  (It was a couple of years ago I did this; I think I spammed
m3devel about it then too.)
