cc1plus: all warnings being treated as errors
The error in the program is a simple typo (']' instead of '}'), but gcc only
tells me this after a lot of other errors resulting from the incorrect parse of
the following text -- here exemplified by the a, b, c stuff; in my actual code
this was pages of error messages which made it hard to find the actually
relevant ones (expected ... before ']').
