[The reason I choose Watcom over emx/gcc is that I can compile on linux using Watcom, however the emx stuff still aren't ported to linux making cross-compiling is not possible and that's a big no for me.] -- O.S. _______________________________________________ flac-dev mailing list flac-dev@xiph.org http://lists.xiph.org/mailman/listinfo/flac-dev
