In fact, there was indeed a bug in the code that handled abnormal exit
status of the preprocessor: it would bail out early without showing
the error messages emitted by the preprocessor, which are an important
clue as to what went wrong. For example, if you don't pass any
options to the preprocessor, it fails with this error message:
<stdin>:21:20: fatal error: config.h: No such file or directory
compilation terminated.
which clearly suggests that you need to pass at least the -I. switch.
I fixed this.
