O.k., got your point...

I see...

Which is actually *really* helpful, thanks a lot!  I used ELDK 4.2 happily for years, and was forced to move when the kernel starting with 3.2.50-something failed to compile with it.  My 5200 still u-boots with a /very/ old 4.2 build (never saw a reason why I should re-compile perfectly working code).

For me, kernel and user space /seem/ to work with the 5.5.2 builds.  I only saw some strange effects in user space after the update (delayed or lost signals between processes), though, which (IIRC) were not visible in the 4.2 builds, and which I blamed to me being too dumb (which is probably the case anyway).

I think your approach is perfectly right, so I'll downgrade to 5.4...

Thanks again,
Albrecht.
