VMS can no longer self-host its own development stack any more.

 It depends on what is meant by "its own development stack." It certainly
does self-host the tools used to build the OS itself.

There are lots of compilers and interpreters available on VMS.

FPC has really nothing to do with VMS, but compiling to
Java byte code is a very broad targeting cross compiler.
Which I took advantage of.

 And I think everyone who wasn't trolling recognized that.  The JVM
brings a big party with it wherever it goes.  .NET would bring a
slightly smaller but still nice-to-have party.  With LLVM as a
foundation for the current crop of VMS compilers, many things are
possible (but nothing is easy).
 Has anyone actually tried porting FPC to VMS?  It looks at first glance
like a lot of it is written in Pascal, so I assume it would need to be
cross-compiled initially.
 

Why?  Wasn't the VMS Pascal compiler ported?  I would think it
would be a lot easier porting something written in Pascal
compared to something written in C.
