It wasn't removed, it was just chained to the #if. Now, the 80 char
per line limit in the email does not help in making the code clear, but an
&& !defined(__getreent) was added to the #if.

#if defined(__DYNAMIC_REENT__) && !defined(__SINGLE_THREAD__) &&
!defined(__getreent)
struct _reent * _EXFUN(__getreent, (void));
#endif

By the way, if you tink this makes the code less clear I can provide a
patch that nests the #ifndef inside the #if as it was before.
