--- Comment #18 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
Thanks!
I think I know the reason why it is failing, but I am not sure about the proper
fix.
For some reason unknown to me, push_commandline_include should not be called
while processing -imacros. -imacros tries to achieve this but playing tricks
with include_cursor, but that doesn't stop the pre-included files. Calling
cpp_push_include (or cpp_push_default_include) seems to mess up everything
(again, no idea why!). This code is really a mess but the simple patch below
seems to work. Could you test it?
