That's an error from the preprocessor, so -E is probably working (i.e.
it's not insisting on compiling) but it thinks the input is invalid so
it doesn't produce output.
You could try using -E -fdirectives-only which disables macro
expansion, but still processes directives such as #define and #if, to
see if the results are what you expect.
I will try it but I doubt if it will show me anything effective. The
error it is showing is of the form:
#if SOME_MACRO() == 1 && SOME_OTHER_MACRO() == 2
where it is saying:
error: missing binary operator before token "("
Clearly the error depends on the macro expansion of 'SOME_MACRO' and
possibly 'SOME_OTHER_MACRO()' at that point. But gcc is being supremely
difficult and not showing me what the macro expansions are when I use
the -E option once it gives me the error.
