RE: Trimming uclibc in l4

Hey Markus,

I am using a version from April 2011 but even that version contains a lot of things that bootstrap and sigma0 do not need. :)  Did you mean more recent than that?

best,
ramya

p.s. my board requires that I run an older version of the kernel - so the pain.

Great idea, but you should probably update your L4Re. L4Re features
such a minimal version since about 2011. So no need to do the same work
twice :)
