Seems so, yes. can you come up with a patch that removes 
src/compat/hsearch_r.c plus any references from Makefile.*'s ?
the configure check "checking for hsearch_r" should also be removed from 
configure.ac.


if so please send it here with a title like
"[PATCH]: remove unnecessary/obsolete compat/hsearch_r.c"
and a comment mentioning its removal with the above commit, plus that it 
highly increases portability for non-glibc systems.

thanks.
