Thanks Andrew,
I'll look at mtd distribution, see if it includes Øyvind's patch, and figure
out what to do next based on what I find there.  In the mean time,
experimental evidence suggests that the 'defined(__ARM_ARCH_4__)' should be
'defined(__ARM_ARCH_4T_)' in fs-ecos.c.  At least on my system, which
compiles fs-ecos.c with the following command:

arm-elf-gcc -c  -I/home/wpd/ess/redboot/dbw-redboot-ram/install/include
-I/home/wpd/eCos/ecos-20060228/packages/fs/jffs2/current
-I/home/wpd/eCos/ecos-20060228/packages/fs/jffs2/current/src
-I/home/wpd/eCos/ecos-20060228/packages/fs/jffs2/current/tests -I.
