* This dependency calculator uses the same dependency management technique as the

*
* 1. An echo command creates the dependency file (.d).
* 2. A second invocation of the compiler is made in order to append to the dependency file.
* The additional options -MM -MG -P -w are added to the command line.
* 3. The dependency files are post-processed to add the empty header rules.
*
* This dependency calculator uses the class DefaultGCCDependencyCalculator3Commands
* which implements the per-source command information
*
* This is an example dependency calculator that is not used by the CDT GCC tool-chain.
*
* @since 3.1
* @noextend This class is not intended to be subclassed by clients.
