gcc/cpp preprocessoor continue on error

[Paul Hansen <paul.hansen.name@xxxxxxxxx>]

Hi
Using gcc/cpp preprocessor on Mac
$ cpp -P -E -I <dir> myfile.h
cpp continues when it cannot find an #include file in myfile.h

Using the same on Linux, it stops preprocessing when an #inlucde file
is not found.

Does anyone know if I can make cpp behave on Linux as on Mac.
I have searched for hours but in vain...

Thanks
Paul
