This header defines macros for alternative operator spellings.

Synopsis

#define and     &&
#define and_eq  &=
#define bitand  &
#define bitor   |
#define compl   ~
#define not     !
#define not_eq  !=
#define or      ||
#define or_eq   |=
#define xor     ^
#define xor_eq  ^=

Notes

This header is meaningless in C++ because these macro names exist as keywords in C++ and are unconditionally available.
