So, the previously-questionable newlib alias-to-offset-in-table kludge is finally judged invalid. This is a heads-up for newlib users. IMHO it's not a GCC bug, though there's surely going to be some commotion. Maybe a NEWS item is called for, I dunno.
It will be in NEWS, since RTH already updated http://gcc.gnu.org/gcc-4.0/changes.html. I hope newlib will be promptly fixed.

I have just checked in a patch to newlib that changes the ctype macros to use __ctype_ptr instead of _ctype_. In addition, a configuration check is made to see whether the array aliasing trick can be used or not.
The code allows for backward compatibility except in the case where the old code is using negative offsets and the current version of newlib is built with a compiler that does not support the array aliasing trick.
Corinna, if this causes any Cygwin issues, please let me know.
