Subject: autoconf probe for uintptr_t size patch v2
Authentication-results: sourceware.org; auth=none

Hi,

I wondered why there were no comments and apparently this
didn't actually get out. I didn't see it in the newlib mailing list
archive anyway.

This is the second version of the patch with the second check only
performed if it is needed. Now includes regenerated configure file.
I regenerated it with autoconf 2.64.

OK to commit?
