Commit Message

Building a zTPF cross currently fails when building libstdc++
complaining about the __UINTPTR_TYPE__ to be missing.

Fixed by including the glibc-stdint.h header.

	* config.gcc: Include the glibc-stdint.h header for zTPF.

To confirm: TPF provides a <stdint.h> header, which uses the same types 
as glibc's <stdint.h> does?

If so, you can remove TPF from the list of targets for which bug 448 has 
yet to be resolved.  (If TPF doesn't provide <stdint.h>, you should set 
use_gcc_stdint=provide for TPF in config.gcc.  If it provides it but using 
different types from glibc, you'll need to add a host-side header 
describing those types instead of using glibc-stdint.h.)

TPF uses an older version of Glibc. So they have stdint.h and the C99 types. Only the *_WIDTH macros
appear to be missing in their version.
