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'.
