Presumably your compiler has a flag to enable C99-or-better mode. If not, you're out of luck: Gnulib assumes C99 nowadays. If so, please investigate why 'configure' did not set that flag.
With ancient GCC, 'configure' should try the -std=gnu99 option; why didn't that work for you? Please check your config.log to find out.
