where do they claim this? i see a claim that they
accept cfront-isms, but that's a different claim.
Quoting http://comeaucomputing.com/faqs/genfaq.html#ccompiler
"Input C++ code is translated into internal compiler trees and
symbol tables
looking nothing like C++ or C. As well,
it generates an internal proprietary intermediate form.
But instead of using a proprietary back end code generator,
Comeau C++ 4.3.3 generates C code as its output."
Isn't that what cfront did, more or less?
Not really, no. In their case, I believe, C language is treated
as an intermediate language. It has no traces of the Cisms
of the original C++ code. It is as mangled as an assembler
would be if you do g++ -S foo.cc.
cfront (well, at least the original one) still preserved most
of the original code (as do most of thing like cyclone, cilk, etc.).
