[PATCH] move the computation of C++ warning flags to bfd/warning.m4

- Subject: [PATCH] move the computation of C++ warning flags to bfd/warning.m4
- Authentication-results: sourceware.org; auth=none
From: Trevor Saunders <tbsaunde+binutils@tbsaunde.org>
Hi,
There isn't anything specific to gold about this code, so it would seem to make
sense to compute C and C++ warning flags in the same place. This also means
that anything else that wants C++ warning flags won't have to roll there own.
The only real difference between the C and C++ flags other than getting rid of
flags that don't make sense, and so don't exist in C++ is removing -Wshadow
because currently the bfd headers aren't compatable with it.
I tested this produces the same set of warning flags for gold/ as before, ok?
Trev
