Hi,
Several older compilers fail to build modern GCC because of missing
or incomplete C++11 support.
(although the PR mentions clang, specifically, this has also been reported
for some GCC versions within the range that should be able to bootstrap
GCC)
There are several possible solutions proposed in the PR, this one seems
the least invasive.
The header is pulled into the gcov code that builds with C, so we have to
make the CTOR conditional on C++.
tested on Darwin12 with xcode-6, bootstrapped on x86_64-darwin and linux.
OK for master / GCC-11?
thanks
Iain
