you like the current style or what I propose?

if I would start up now to use hidden, I would have at least been doing
leave func() {} as it is
append libc_hidden_def(func) where
libc_hidden_def(func) hidden_strong_alias(func,__func) (I came on to this 
idea too late)

Until uClibc-1.0 is released versioning is not needed (we can always say, 
the new version is incompat w/ the earlier, please rebuild). After that I 
am not sure ...
