When you just use memset in eCos application, most probably it will be
taken not from newlib, but from eCos own C library. You can easily check
what is linked by searching for 'memset' in the map file generated by the
linker. In my case 'memset' is taken from
ecos/install/lib/libtarget.a(infra_memset.o).

Anyway, there should be no harm using 'memset' from either newlib or
eCos from DSR, unless there are some xscale-specific issues I'm not
aware of.
