The `LIT64' macro takes as its argument a textual integer literal and

if necessary ``marks'' the literal as having a 64-bit integer type.

For example, the GNU C Compiler (`gcc') requires that 64-bit literals be

65
appended with the letters `LL' standing for `long long', which is `gcc's

66
name for the 64-bit integer type.  Some compilers may allow `LIT64' to be
