I've finally decided to put my two cents in.
It is not necessary for C variables to be prepended with _,

In fact, the C compiler used on our 68020 box does not prepend _,
and it works fine.  I am not a compiler wiz, but I do know that
the assembler requires register names to be prepended with %
and immediate data with &.

This has caused a very few (very minor) problems,
and we are pretty happy with the compiler.

The compiler is a system V coff format compiler.
Is this treatment of _ generic to system V?
Getting one extra character of significance in identifiers
was not the reason it was done, (the compiler already
supports long names).
