I am attempting to port C++ 2.0 (using AT&T source code) to a machine
which uses the "volatile" type specifier in its C header files. Cfront
2.0 strips out volatile in the mangled C output, and gives the message

warning: " volatile" not implemented (ignored)

I can think of 2 possibilities here:

1. filter the headers before and after cfront, e.g., convert all "volatile"
   to /*volatile*/, then back
2. find the place in the source where volatile is stripped and change it

1 is less than ideal because it would break if the word "volatile" appeared
in a comment (though I suppose I could work out a safer transformation..).
2 might break in some declarations that don't translate directly into
simple C. For that matter, why _is_ volatile not implemented?

Any comments or suggestions would be welcome.
