These platforms hide the declarations + when gcc is in -ansi mode, by testing for __STRICT_ANSI__. Turns out, + however, that -U__STRICT_ANSI__ on the gcc command line strips this + away, causing the declarations to be revealed. + + * lib.c, parser.l, stream.c, utf8.c: Removed the declarations which + compensated for the above problem.
