There are in fact lots of commercial PL/1 compilers out there....

Liant.com claim to have implemented the "full IBM PL/1 features" and at
the same time to be compatible with DEC, DG, Wang, and Prime and their
compiler runs on many platforms.  Of course IBM have their PL/1 compiler
available on most of their supported OS platforms.

I remember rumours of someone writing a PL/1 parser front-end for the
GNU compiler (i.e. egcs), and I don't see why it would be that hard
given the resources.  After all there's an Ada parser for it!  ;-)
