Emit the preprocessed input file only, do not compile

Syntax

` -pp

`

Description

The -pp compiler option enables the preprocessor-only mode. The code is parsed & checked as usual, but is not compiled. For every input file .bas passed to the compiler, a pre-processed version named .pp.bas is generated.

Specifically, preprocessor commands such as conditional compilation (#if, #ifdef, #ifndef, etc.), text replacement (#define, #macro, etc.) and file inclusion (#include) are processed recursively, and the resulting expanded code is written to the pp.bas file.
