The first allows usage of several functions in the std namespace, which
broke compilation of gddrescue specifically with uClibc-ng and uClibc++.
The second allows usage of long long with normal C++11, which is part of
the standard. Before, std=gnu++11 needed to be passsed to work around it.
As a result of the second patch, the pedantic patch can safely be removed.
Both patches are upstream backports.
Added -std=c++11 to CFLAGS to guarentee proper inclusion of long long.
Added another patch that fixes a typo with the long long support. Sent to
upstream.
Fixed up license information according to SPDX.
Small cleanups for consistency.
