/* The following provides an inline version of __getreent() for newlib,
which will be used throughout the library whereever there is a _r
version of a function that takes _REENT. This saves the overhead
of a function call for what amounts to a simple computation.
The definition below is essentially equivalent to the one in cygtls.h
(&_my_tls.local_clib) however it uses a fixed precomputed
offset rather than dereferencing a field of a structure.
Including tlsoffets.h here in order to get this constant offset
tls_local_clib is a bit of a hack, but the alternative would require
dragging the entire definition of struct _cygtls (a large and complex
Cygwin internal data structure) into newlib. The machinery to
compute these offsets already exists for the sake of gendef so
we might as well just use it here. */
