[antlr-interest] Error parsing Linux Kernel Files

[Bernhard Poess]

Hi,

I'm trying to use the cgram grammars to parse files from the Linux
Kernel, but I get many exceptions doing that. Should'nt the GNU C
grammar parser be able to parse Linux kernel files:

Error Message:

I've attached the source file.

Any help with this would be very appreciated.
