Don't know.

Code does wrong thing.
The "-finit-priority" command line option no longer exists in GCC 3.4.2,
so I had to remove it before I could compile my app. I believe this to
be harmless though.
What I observed was that my initialisation routine was getting called
before pools where allocated, instead of before as with the toolchain
that I downloaded from sources.redhat.com/ecos.
When I modified the code as in the patch, things went back to "normal".

It would be nice to have a consensus from the eCos community before I
shout "compiler bug!" :-)
If my observations are correct then surely this is a compiler bug... Or
perhaps a problem w.r.t. how I built the compiler or somesuch.
