parser: use int64_t for all numbers Don't use int which can have different size on different machines. Also avoid some warnings from MSVC: xkbcomp/parser.y(760): warning C4244: '=': conversion from 'int64_t' to 'int', possible loss of data xkbcomp/parser.y(761): warning C4244: '=': conversion from 'int64_t' to 'int', possible loss of data xkbcomp/parser.y(767): warning C4244: '=': conversion from 'int64_t' to 'int', possible loss of data Signed-off-by: Ran Benita <ran@unusedvar.com>
