Yes, this seems like a thing we should do.

Embed the "architecture" name in a shared libperl, and in the the main()
routine, and bail out with a helpful message if the two disagree.

Do we actually need a function to do this, or is it portable simply to define
a global static string, and compare it with a local static string in "main()"
(by "global static string" I mean the same mechanism as the other global
static strings)

No, sorry, I wasn't clear. I'm not.

Relocatable perl is most definately do-able. Windows was ahead of the game
here - the mechanism is only just in for *nix.

But the default configuration on *nix is to have the perl executable contain
the Perl C library routines (so that the executable around 1M). The
alternative, having a shared Perl library (typically named libperl.so)
with those routines, and a


What we (this list) wasn't sure was easy to do was to solve chicken-and-egg
