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'. | |
