Actually, NEED_DECLARATION_xxx depends on the macros GCC_NEED_DECLARATION(S)
which are not part of autoconf and are defined in gcc/aclocal.m4.
Should they be copied into a libiberty/aclocal.m4 (I'd prefer not to),
or may libiberty be considered to be a part of gcc ? (I don't think so,
as it is also included by binutils)
Then, to make it clean, one should have a `system.h' file, like in gcc
where all those conditional declarations would be kept.
If we see it the other way, we probably could let libiberty do all
the configure work, and enhance libiberty.h
to provide those missing declarations and use libiberty.h everyhwere
instead of system.h, or whatever it is called elsewhere.
