Re: [PATCHES] snprintf() argument reordering not working

OK, a few things.  First, Tom has fixed snprintf.c so it should properly
process positional parameters now.  Would you first test the libintl
version of *printf to see if it can process %$ parameters (probably by
hacking up any language file and testing the printing), and then try
your patch below to see if it is properly reorders the arguments.  If
libintl does not reorder properly, but our snprintf.c does, would you
please generate an appliable patch we can put into 8.1.X?  Thanks.

I know I am asking a lot, but you are "the man" on this one.  :-)
