Handling error message from cpp "header toto.h not found".

[gryken2014]

Problem :

• pycparser analyse a c source file,
• the c source includes a header file, which doesn't exist.

cpp print a message like "header toto.h not found", on the console.
But pycparser doesn't handle this message, and the analysis is done anyway.

Proposition :

• handle this kind of messages (read from stderr, when cpp is launch),
• create an exception to stop the pycparser analysis, and avoid a false analysis

Thanks for you help

pycparser's main goal is to parse correct C code. The parse_file function is just a thin helper over the parser, and I'm reluctant to add too much functionality to it (like examining return codes from different kinds of cpp programs).

Feel free to implement your own variant of parse_file that does exactly what you need.
