[PATCH] Fix stdin,-out and -err for multithreaded apps

[Thomas Pfaff]

Attached is a patch that should fix the bug reported at

http://sources.redhat.com/ml/newlib/2003/msg00544.html.

which is another __DYNAMIC_REENT related problem.

It will change stdin, -out and -err locations to use _GLOBAL_REENT 
instead of _REENT where appropriate, and it includes a change for the 
stdin, stdout and stderr defines that i suggested some time ago (see 
http://sources.redhat.com/ml/newlib/2003/msg00363.html).
This will allow to change stdin, stdout and stderr without recompiling 
all user apps in the future.

If speed is an issue the former defines can be used by defining 
_INLINE_STDFP.

After applying this patch Makefile.in must be regenerated.

Comments are welcome.

TIA,
Thomas
