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.
