Dear all,
I have a couple of files that needs to be proprocessed with the -E.
However in the output there are too many undefined symbols like __builtin_valist or others.
Do you know how to remove them from the output?
The files uses standard gcc libraries.

Alternatively, do you know tools that make function/include/define/struct etc. expantion, without been compiler/so dependent?
thank you in advance for your replay
