Re: Bignum support

I'm also thinking about compiler declaration to force fixnum arithmetic, but that's maybe not necessary in XEmacs because we don't generate native code. Most importantly, how much of a slowdown to you expect? Every XINT will need to be reviewed and changed into one of: * XINT_FIXNUM: convert fixnum to integer, argument must be fixnum. Caller should have run CHECK_FIXNUM. * XINT_COERCE_FIXNUM: convert fixnum or bignum to integer, but throw an error if the bignum is not representable as integer. Caller should have run CHECK_INT. * XINT_ANY: convert fixnum or bignum to a C object that represents bignums.
