multiple definitions of assert

[Daron Chabot]

I've tripped over this bug building Till's GeSys app:

I'm using binutils-2.19.1, gcc-4.3.3, and newlib-1.17.0 with the
latest patches for all.

RTEMS itself is from the cvs HEAD (last week).

Till pointed me at this thread:
    http://www.rtems.org/ml/rtems-users/2009/march/msg00042.html

It seems one multiple definition has slipped through...

I've attached a patch to cpukit/libcsupport/__assert.c to allow my app
to compile, but I'm not sure whether the fix properly belongs in RTEMS
or in newlib ?

Thanks.
