46: # Unfortunately, we do not know which of the symbols are generated by
47: # the toolchain. Worse, they vary from platform to platform and
48: # toolchain to toolchain. The good news, however, is that this will
49: # be detected by a compile-time failure, so we can fairly easily manage
50: # a quirktable here.
