We should make it easier for the user to keep the build-settings in sync with the compiler inspection done as part of the scanner discovery. Many of the compiler options influence the predefined macros and/or the predefined include search path. The option -std=c++0x is just an example for that.

There are probably two use cases:
(1) Managed build:
    The user has to add the compiler option for the build and separately
    he needs to adjust the command-line for the compiler inspection.
    Can we reuse the settings specified for the build?
(2) Unmanaged build:
    The option has to be defined somewhere in a makefile.
    Can we grab the compiler options via the build-output parser?

This would be extremely useful for mixed C/C++ projects, where one configuration builds a given file as C, and another configuration builds the same given files as C++. It's also extremely useful since specific files being compiled with -std=c99 or -std=c++11 will have slightly different built-in symbols.
