I don't think that is needed, and we'll probably need that line in its
current form in future versions.

I sent another two messages to the list, but found they were rejected,
I'll repeat below:

I committed r5525 and uploaded to Ubuntu, and I have already received
negative feedback. :(

I inadvertently had hardening-wrapper installed on the 3 different
machines I used for testing.
This caused symlinks for gcc-4.4, gcc-4.6, gcc-4.7, gcc-4.8 and
gcc-4.9, etc. all to exist, breaking Andreas' wrappers.
I thought I could rely on gcc-4.9.real, but this turned out to be
installed by hardening-wrapper as well.

I'll try to find a more robust solution.

The most reliable way I have found is to run 'g++-4.9 --version'.
i.e. debian/g++ would become:


if g++-4.9 --version >/dev/null 2>&1; then

exec $prog "$@"

Any other suggestions?
