I am not sure the actual semantics exactly match up, ie this call 
mallocs and returns a buffer that needs to be freed. The call is part of 
the SUSv4 I have handy and I assume newlib is supplying a suitable header.

I only added it because the editor uses it when printing the actual name 
in the status line.
