Ok, so I'll guess that comeau.hpp is "required" to include common_edg.hpp?
Hmmm, let's see...  Ok, yes.

For as long as I can remember __EXCEPTIONS is set when --exceptions
is set (whether implicitly or explicitly).

Of course though, a particular vendors is free to ignore this
and/or change that name to something else.

On this note, be careful with common_edg.hpp (although there is
not much in it) because probably many vendors toss __EDG_VERSION__
(I think I had done so very early on).
