Pragmas to control the layout of listings

The layout of source, error, and preprocessor listings can be controlled from within the source text by means of #pragma directives. Other listings generated by the compiler cannot be controlled by pragmas.

The -K pragmas_interpreted, -K pragmas_ignored and LISTING-PRAGMAS=... options can be used to globally specify which of the pragmas that appear in the source text are to be interpreted or ignored.
