Allow checking multiple defined conditions with one /IF compiler directive

Checking multiple defined conditions is cumbersome - if a part of code should only be combined when two conditions are defined, one has to use nested /IF directives:

/IF DEFINED(condition1)
/IF DEFINED(condition2)
// code only compiled when condition1 AND condition2 are defined
/ENDIF
/ENDIF


This could be easier and more concisely coded like:

/IF DEFINED(condition1) AND DEFINED(condition2)
// code only compiled when condition1 AND condition2 are defined
/ENDIF


If a part of code should be compiled when wether condition1 OR condition2 is defined, this can only be coded by duplicating the code part:

/IF DEFINED(condition1)
// code only compiled when condition1 OR condition2 is defined
/ENDIF
/IF DEFINED(condition2)
/IF NOT DEFINED(condition1)
// code only compiled when condition1 OR condition2 is defined (duplicate)
/ENDIF
/ENDIF


This code is hard to read and understand - it would be much more readable and concisely coded like this:

/IF DEFINED(condition1) OR DEFINED(condition2)
// code only compiled when condition1 OR condition2 is defined
/ENDIF


From my point of view, this extension would not collide with existing code, while giving new code opportunities to be more expressive, concise and readable.
