r18266: we should bail out in configure if C99 structs are not support

tridge: I think we should create macros in libreplace_macros.m4
        and call them in check_cc.m4 instead of running the tests
	in libreplace.m4. Maybe the macros should remember if they're called
	and then they're skipped in libreplace.m4 inside samba4
