Regarding the thread about what language Ada 9X compilers are being written
in,  DDC-I Ada compilers have always been written in Ada.  When work began
on upgrading to 9X, the question was reopened as to what language to use
for the components being built from scratch, with Ada (83 -> 9X), C, and
C++ all considered.  Overwhelmingly, the staff was in favor of Ada, and
that is what is being used.  Notably, the feeling on the side of Ada seemed
to be strongest amongst those who had used C or C++ on other projects!

Also, as a general rule (with notable exceptions I'm sure), compilers are 
best if written in their own language.  First, it means the compiler developers
will have a genuine "feel" for the language and its uses, rather than what
you get from just reading an LRM.  Second, it means the compiler developers wil
l
have to use their own compiler and their own tools, which is a great if
"selfish" incentive to make them even better.
