Agreed. But if that will be really needed. I would trust the eCosCentric
test results for ARM7 target.

It's clear. I did not suggest to follow all next 4.6 derivatives.

Good to know.

Today I tested a bit and GCC 4.6.3 based build (just for case)
http://ecos.sourceware.org/ml/ecos-devel/2012-03/msg00002.html

And as I told I had no problems with the contributed toolchain too,
though, my test "farm" is a very little farm (1-board stall), so, I
decided to point on that bug-fix here.
