Yes I know :-)

Ok.

I know I've seen this problem before.  I don't remember the exact
details, but I believe there was a bit more wrong here dealing with
the VxWorks loader's restrictions on the number of segments in
executables.

We have more patches to be submitted for vxworks:

* enable --gc-section with -r and -q: we think this is a very useful feature for vxworks.

* merge gc sections with -r: the patch is not yet ready to be submitted as I think it would be better to have a new flag.

Tristan.
