Well, I see that this problem is already addressed for a year.  I have to 
admit that soft-fp build for targets, which aren't based on glibc, is a 
bit loud due unprototyped functions and some potential uninitialized 
variables, but all in all nothing serious.  So I am patient that this 
latent issues get fixed on glibc.

Yes, sorry for being unclear here. Of course warning is shown by produced 
4.6 based compiler.
