stdout is a global variable, for starters.
All open files are kept in a static array in
fact. No way that will survive. Some of the
assembler is non-reentrant too, although it
looks like it has been removed from the MVS
version. The CMS version has this:

         MVC   ATTNOD,0(R5)
...
ATTNOD   DC   CL4'XXXX'     WHERE ORDER MAY BE LIFO OR FIFO.

Although even that doesn't appear to actually
be used.

So I guess it's pretty good.

But unless things like stdout are reimplemented
to reference a CRAB, with a dedicated register,
you're not going to get very far.

Note that Robert O'Hara has done some of this
reimplementation already in his GCCLIB, and he
did it with intrusive code rather than changing
the compiler (and losing a register). The
intrusive code would appear to be the superior
option for the exact situation he has though
(PDPCLIB as a shared DLL, basically).
