The primary reason why do_rm was added was to be gentle to shells which do not
do bash-like globs. Please refer to the samples on trunk.
PS: It would be nice if we would move to use something like $(call do_rm,)
mid-term since with that it should be easier to pretty-print the dirname of
the affected files once and correctly (as you can see i cheat with the names
a bit right now). Any volunteers?

Hi Bernhard,
it should be fine now (rev 24254). Thanks for pointing this out.

__THROW and cancellation point patch.
Last March, I made a suggestion to this list: That the many functions which are cancellation points, but would otherwise never throw C++ exceptions, be marked with a "__THROW_CP" macro. This would be a no-op on threaded builds of uClibc, but would be equivalent to __THROW for a threadless build. This would produce a tiny optimization boost for threadless builds, and more importantly, would make the include files much clearer. No longer will every tenth line be part of a comment explaining why __THROW is not applied to a given function. There was no response, probably because while the idea is simple, it requires a lot of typing to implement. Well, I'm back, having done the work. I now have a patch available at: ftp://ftp.ocis.net/pub/users/ldeutsch/beta/uClibc-0.9.30-throwcp.diff The patch adds "__THROW_CP", and applies it to every function previously having a "such-and-such is a cancellation point and so not marked with __THROW" comment. Additionally, fputw(), fgetw(), and BSD sigpause() have been marked __THROW_CP. sigpause() was formerly __THROW, which looked wrong to me. I'm "dogfooding" the patch, but that doesn't really count for much since I don't use C++. I'd be interested to see any heavy-duty exception users try it out, both to see if it helps the unthreaded case, and verify it does not break the multithreaded case.
