[PATCH] (Re: Query concerning use of flockfile/funlockfile in stdio FILE related functions)

[Antony KING]

Please find attached a patch to newlib (CVS snapshot 10-Sep-2004) which 
solves the problem I was having with being able to use sprintf/sscanf et 
al from RTOS contexts where using locking was not permissible and where 
no REENT structure exists.

Please note that I have re-enabled the definition of _GLOBAL_REENT to be 
_global_impure_ptr when not CYGWIN; I hope this compromise is OK.

I have also made a number of other minor changes which I also hope are 
OK (missing documentation, missing initialisations, default tz_lock 
implementation a la env_lock, walking GLOBAL_REENT multiple times).

Cheers,

Antony.
