Let me start by saying 6.4 is totally unsupported, but you are most
likely aware of that. :-)

That said, I don't think 6.4 already had complete C99 support, so this
is probably why the configure script fails.  You can see the script
itself gives you a few hints for a workaround.  Since 6.4 is already
using a gcc version older than 4.3, and the "fix your include files"
hint is only valid for glibc, the best option is to make sure -std=c99
or -std=gnu99 is *not* used.

For example, if you are building this manually, try setting
ac_cv_prog_cc_c99=no in configure's environment, like so:

  ac_cv_prog_cc_c99=no ./configure

If you are building this from the port, try adding a line:

  CONFIGURE_ENV+= ac_cv_prog_cc_c99=no

in the port's Makefile.
