OT: Is this the right list? - [Fwd: #line and g++]

[Aldo Dolfi <dolfi at ccrl dot nj dot nec dot com>]

Hi everybody,

I posted this message yesterday and got no answer. I know
that I should not expect that every question gets its
answer :) but I would like to know at least if this is
the correct list to ask this kind of question or not.

I tried to search for other places but, apart from general
c++ discussion I found nothing. And I think this is an issue
specific of gcc. I did not find anything in docs, either.

Do you have any suggestion?

Thank you
Aldo Dolfi
