[fpc-pascal] Range check error warning.

[fredvs]

Hello.

With fpc 3.3.1 there is this warning:

"Warning: (4110) Range check error while evaluating constants (-193 must be
between 0 and 255)"

Here the code pointed by the warning:

const
 foldhiddenbit = 7;
 foldhiddenmask = 1 shl foldhiddenbit;
 currentfoldhiddenbit = 6;
 currentfoldhiddenmask = 1 shl currentfoldhiddenbit;
 foldlevelmask = byte(not (foldhiddenmask or currentfoldhiddenmask));
-------->Here the warning

I dont understand how the compiler can find -193 as value for
foldlevelmask...

Fre;D
