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

appended with the letters `LL' standing for `long long', which is `gcc's
|
|
name for the 64-bit integer type. Some compilers may allow `LIT64' to be

defined as the identity macro: `#define LIT64( a ) a'.
