The Fourth installment, testing and other oddments will be sent tomorrow.
The implementation of __has_cpp_attribute is underway and will come in a
few days as a Fifth installment (modulo bugs this should be all).
I have it working in C++.
I feel though that it would be welcome as it is in clang for all
C-family languages. I intend to offer a __has_attribute for all C
languages.
The __has_cpp_attribute will just be for C++.
Thiago, I did not mean to clobber your work. This has been baking for a
while (last patches in June) and I just got back to it after a break
with little useful attention to g++.
Perhaps we can combine our work. I'll look over your patch. I know you
want this to support Qt ;-) I think this effort will help.
Sincerely,
Ed
