Linux 2.4.18a ?
Never heard about it :-)

gcc 2.96 ?
use 2.95.3 or 2.95.4

See $(kernel_root)/Documentation/Changes to find out what you need
for compiling this kernel (where $(kernel_root) is where
your kernel tree is located for example /usr/src/linux )

An unsupported filesystem in your  kernel (i.e. your
filesystem is xfs for example and you don't have xfs
support in kernel)

Could be many things.
