Subject2.6 code size
Hello All,
I know there were some discussions the other day regarding the size
of the 2.6 kernel vs the 2.4 kernel. I decided to see if this was due
to gcc-3.2 being used rather than gcc 2.9*, and I do not think it is.
I configured the kernel and build it under RH9 which uses gcc 3.2.2.
Then I booted into RH7.3 did a make clean and a make (RH's gcc 2.96).
The object file size actually seems to be a little better with 3.2.2:

I used whatever compiler options the 2.6-test1 Makefile chose to pass
the compiler. I did nothing to change them.

Hope this is useful.

Thanks,

Jim
