gcc 3.0 and linux kernel

[Kashif]

Hi,

I am using a compiler which supports gnu extensions uptil gcc 3.0. As
gcc is used to compile the linux kernel I was wondering at max which
kernel version can be compiled with gcc 3.0? Or is it the case that
gnu extensions with gcc 3.0 are pretty much the same as those that are
supported in the latest release?

Thanks,

Kashif

This is not really a question of the capabilities of gcc but rather of
how the kernel is coded.  It is tied very closely to gcc, to the point
where it has a number of version-specific #ifdefs.  It's really more a
question for LKML than here.

You should read the file Documentation/Changes, which for any given
kernel should tell you the minimum required version of gcc.  As far as I
can tell, kernel 2.6.16 (20-Mar-2006) dropped all support for gcc < 3.2
so don't even bother trying to compile it or anything more recent with
your ancient gcc.
