Monster _r patch: try to scan for all known _r variants,
and then use them (under ithreads). May fail in HP-UX,
and the op/groups is known to be fickle everywhere. Known
to work in Solaris, Linux, Tru64, IRIX, AIX. (Some compiler
warnings in AIX since the first arguments of getnetbyaddr
and getnetbyadd_r are of different types. Thanks, IBM.)
In non-Configure platforms deny the existence of any
of the _r thingies. (Also add the recently introduced
d_tm_* to places it wasn't already in.)
TODO: the suggested glibc buffer growth retry loop in case
some entries (at least for: gr*, host*) are big.
Forgot win32/config.win64.
