It can bite you on any platform, but most often Windows.  Unix dynamic
linking is more delayed and 'dynamic'. So you can statically link in a
library with your Lua 5.2. The trouble happens at runtime when a Lua
5.1 module is brought in, and yells that it can't find some deprecated
API function.  (Which is deliberately made hard, they sit in different
directory trees.)

Nick's problem is that he does not want to control what people do with
his software. So they'll find a Lua 5.1 extension and of course it
won't link or (worse) it will half-work because of the allocator
issues discussed. You get this also with different MS runtimes even
with just Lua 5.1.
