Warnings should be okay in these decl tests, and it looks like they
passed.  (You claimed in your first message that they didn't, right?)

And it looks like HAVE_SYS_RESOURCE_H was defined here, or you
wouldn't get sys/resource.h included to cause the conflicts.

Right, you need to zero in on why HAVE_SYS_RESOURCE_H isn't being
defined by autoconf on your system.  Also, why was it defined during
the decl check, but not here when compiling gcc.c?
