    The syntax for that is one of the following:

    # define STR(x) #x
    # define XSTR(x) STR(x)

    # define SOME_ARCH_DIR foo/bar
    # define STRING_INCLUDE(path) XSTR(SOME_ARCH_DIR/path)
    # define ANGLE_INCLUDE(path) <SOME_ARCH_DIR/path>

    # include STRING_INCLUDE(baz.h) ==> # include "foo/bar/baz.h"
    # include ANGLE_INCLUDE(baz.h) ==> # include <foo/bar/baz.h>

    I'm not sure what GCC version these were first supported in, but I
    would try to stay away from them as a matter of principle. They're
    ugly and quite hard to read/understand. If there were no other way,
    I might use those, but since there probably is... I dunno about
    you, but those are some really icky constructions.
