expr is an expression with constants, standard operators and/or preprocessor
identifiers. Code is any standard c source code.
The pre-processor evaluates the constant expression and if it is non-zero will
process the lines up to the optional #ELSE or the #ENDIF.
Note: you may NOT use C variables in the #IF. Only preprocessor identifiers
created via #define can be used.
The preprocessor expression DEFINED(id) may be used to return 1 if the id is
defined and 0 if it is not.
== and != operators now accept a constant string as both operands. This allows
for compile time comparisons and can be used with GETENV() when it returns a
string result.
