Dear Art,
(Snowball messages should be sent to snowball-discuss@lists.sourceforge.net)
I can hardly criticise you for using Borland 5.1 when I see that my own
version is Borland 4.02! It is a while since I've used the Borland system,
but I recall a clear distinction between warning and error messages, and
would have thoughts its complaints about operator ambiguities ought to fall
into the former category.
Have there been versions C where the binding powers of operators was
different from the contemporary ANSI C definitions? I find it odd how
compilers so often attach importance to this stuff.
Anyway, the fully bracketed expressions are of course
if (min == (1<<16)) error(a, 16);
for (i = 12; i >= 0; i -= 4) write_hexdigit(g, (ch >> i) & 0xf);
bit_is_set(symbol * b, int i) { return b[i/8] & (1 << (i%8)); }
Tell us how you get on. It will be more of a problem if you hit the same
thing in the C output generated by Snowball.
