Try configuring with CPPFLAGS=-Dwhatever or CC="gcc -Dwhatever". (The
latter may be more reliable.)

"struct timezone" is legacy crap that's only defined if -D_GNU_SOURCE
is used. It's probably the same issue as configure not detecting
sigset_t etc.
A better question would be: why are they using struct timezone? It is
*absolutely* *useless*. Probably you should just submit a patch to
remove it.

This I can add - afaik RLIM_* is in the reserved namespace for
sys/resource.h.
