build: add -std=c++03 (in non C++11 mode) and -pedantic to the default CXXFLAGS
And fix the resulting warnings. The long-long-int warning is explicitly
suppressed because it's not trivial to workaround in a platform-independent
and ISO-conformant way without using C++11.
This commit also includes fix for the advisory check for C++11-enabled
compiler in common.hpp (gcc < 4.7 does not correctly define __cpluplus
macro).
Finally, when custom CXXFLAGS are specified, --with-c++11 does not force
-std=c++11 or -std=c++0x flags, but just performs mandatory checks for
std::shared_ptr and std::function.
