The standard allows "char" to be either signed or unsigned. The ARM ABI defines char as unsigned. I recall that Lattice C on the M68K allowed either signed or unsigned char via a flag. Setting it to "unsigned" generally produced faster code on my Amiga, though some code assumed signed chars and broke. --=20 Peter Jeremy --r5Pyd7+fXNt84Ff3 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEE2M6l8vfIeOACl4uUHZIUommfjLIFAl6/NENfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldEQ4 Q0VBNUYyRjdDODc4RTAwMjk3OEI5NDFEOTIxNEEyNjk5RjhDQjIACgkQHZIUommf jLLttA//TGylmpSPxJFCYnXAVQnNijLnCl9phUV+8oqJU8z8zV41HCBnr7o0YOQU NxiFI10WbYcYBI1ThLlEstcRe8sWBg/1LZTNbcfpFB7Z/KyETgnCXDAnSdEMD/5y l+ANVjifF/wXES9yiG7+LIWPXiFyGXz4zi+6VWVrqlk0Od+HJE88Ln9d1rYrMPpx JgAIIx/w9Ui8Wu5hi5KOr2nfHBfrUBWHMpPcF92ByUEBR316fEwSKX6i72jdXDnR 70c3lETk4J9EXlPaOWORLaEz926Is4fp17n3ZHgRLWFcTfHkJenqfZ5lulJpdQHg h0U9ULPNiU5Fo/1bE+JjM2eLODa2ZlidQSXi7Vn25dMfgAlg4PesgwlSJgWrXFfR oKUzSlGX0ZtAF5SqKAOkuzMmG9ASJkSHBxpHvHoAST79OBNXgwMYVO7/03xBXZiy p+13Q8g3L0wEFirg125KDy9TR8re0L6ZrGDDUj4CMRx/83lZxU6qnJdkZXqbce6y txvTQ5MV/cwecaIxZpwoyapB4ohQI7dqALqPyZoX2M2yBjyFai/mumJ0kDh3fD4e zsluxXj3lmDJE3amjtkTkPQFYy9IJ0b+P4XObT7uXvZDIOEClHeAl5G+NtV2XLMo hnalRjHHHKUrQrG/F5EpRNk+thOke8kLwsdNQJMk4Env5DcnIOA= =P+ap -----END PGP SIGNATURE----- --r5Pyd7+fXNt84Ff3--
