That's always a bug to include any gnulib-provided header prior to
<config.h>.

We've managed to modernize other headers to properly declare replacement
structs exactly once; it is merely a matter of someone having enough
time to modernize the gnulib getopt module to use modern constructs
rather than abusing config.h to define an rpl_ prefix.
