It also only generated code for VAX and Interdata. When BSD was ported
to the hp300's GCC became the CSRG's base compiler.

Get real!! For one thing, a new compiler isn't Ph.D. thesis material.
One aspect of a compiler would be -- say a new optimizer, or really
revolutionary parser, etc..
Also, now that we have an ISO standard, creating a good quality C
compiler (I won't even go into C++) is no longer a one person task --
much less one to be done in 1-2 years (about the max amount of actual
creative coding a Ph.D. puts into his thesis). This is way out of the
reach of a Masters project.

Very bad assumption. I've taken three and all where very different.

Exactly.

Yep.
