My AIX machine is (supposedly) unavailable at the moment but I will probably investigate why -qlanglvl=*c99 is not being used when I get a chance.For what it's worth, we should be encouraging that anyway. AC_PROG_CC_STDC should add -qlanglvl=extc99 to CC, and if this isn't working then we should fix AC_PROG_CC_STDC.It's not an issue on AIX 5.1 because 5.2+ introduced va_copy in /usr/include/stdarg.h.
I wasn't talking about va_copy, I was talking about the general problem of configure not figuring out to use -qlanglvl=*c99. This *is* an issue for coreutils on AIX 5.1 (because otherwise one must use the c99-to-c89 patch when there is a c99 compiler available). We have the same underlying problem, with two completely different causes.
