If you are using a makefile based system, simply inspect the files in the
build tree named "flags.make" which you should find in the various locations
where you have customized the flags... If you are using Visual Studio or
Xcode, you can typically find those flags in the properties dialogs of those
IDE systems. Right click on a project node in Visual Studio, for example,
and choose "Properties" -- then look for the "C/C++ > Command Line" entry.
All of your flags changes for a project should be represented in there.
Similarly for individual source files if you have overridden the
COMPILE_FLAGS for individual source files using SET_SOURCE_FILES_PROPERTIES.

HTH,
David
