Description
There are numerous MIN/MAX variables defined during configuration.

Several of the types covered by these variables use the C naming convention by adding "_t" to the type name (e.g. sig_atomic_t, wint_t, ptrdiff_t) but only _RWSTD_WCHAR_T_MIN/MAX has this suffix in the variable name itself. Request making this variable name consistent with the others. (Why? It makes GNU Automake build support that I'm working on much simpler.)
