                <Description>Preprocessor macros to undefine. Undefined macros are similar to defined macros, but replicate the "#undef" directive in source code. To undefine the macro FOO use the syntax "-u FOO" in this setting. This is equivalent to "#undef FOO" in a source file. Note: the syntax differs from macro definition (there is a space, i.e. "-u FOO" versus "-DFOO"). Macros defined with this setting are applied to all .S, .c, and C++ files in the BSP. This setting defines the value of BSP_CFLAGS_UNDEFINED_SYMBOLS in the BSP Makefile.</Description>
