integers of at least as many bits as specified.  For example, `uint8' should\r

The `LIT64' macro takes as its argument a textual integer literal and\r
if necessary ``marks'' the literal as having a 64-bit integer type.\r
For example, the GNU C Compiler (`gcc') requires that 64-bit literals be\r
appended with the letters `LL' standing for `long long', which is `gcc's\r
name for the 64-bit integer type.  Some compilers may allow `LIT64' to be\r
defined as the identity macro:  `#define LIT64( a ) a'.\r

The macro `INLINE' can be used before functions that should be inlined.  If\r
a compiler does not support explicit inlining, this macro should be defined\r
to be `static'.\r
