Right, AFAICT, it affects all newlib-1.17.0 based rtems gccs, not only 
gcc-4.4.0.

Sebastian had pinged me on this issue on PM some time last week and I 
pointed him to the reent.h in response.

However, I haven't had any chance to look deeper into this, because I 
had been AFK most of the time Wednesday through Monday (yesterday), ... 
and am still suffering from backlog effects of the rtems.org mail server 
screwup ;)
