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'.

The macro `INLINE' can be used before functions that should be inlined.  If

a compiler does not support explicit inlining, this macro should be defined

to be `static'.
