No, the new compilers are NOT the old VAX/VMS compilers; they are an
entirely new implementation, from scratch.  I think you'll find they don't
suffer from the problems the VAX C and Fortran compilers did when ported
to Ultrix; these are fully integrated native compilers. 

I can't answer your question about the C compiler; I haven't personally
played with it.  I did get a copy of the fortran compiler to a number of 
heavy fortran user friends of mine, who seem pretty happy with it.

As to the updated MIPS C (2.1) compiler, it actually is on the current
MIPS Fortran kit, and gets installed with it.  It did not become the default
compiler in Ultrix 4.0 and Ultrix 4.1 since it did not recieve sufficient
field testing.  The field test of Ultrix 4.2 I am running has 2.1 as
the default compiler.  (For those of you who might be getting confused,
this paragraph is about the existing MIPS compiler).
