gcc version used to compile Knoppix kernel?

[thincritter]

Hi all,
Can anyone tell me how to tell which vesion of gcc the knoppix kernel was compiled with? I am trying to compile NVIDIA kernel driver and getting an error because the kernel was compiled with a different gcc version.
If I can't find this out I have to figure out how to hack the make file to ignore the gcc version when compiling.
Cheers
Paul
