JFFS linker error in kernel 2.4.19

[Frank R Callaghan <f.callaghan@ieee.org>]

Hi List,

I'm compiling linux 2.4.19 patched with today's CVS MTD patched
with the patching script
(that states 'no Include Filesytems: yes; Zlib-Patch needed: no)

ld -m elf_i386 -T /home/rtlinux/rtai/linux-2.4.19/arch/i386/vmlinux.lds -e

Any Ideas ?
