        Function {\em popfile()} is called from {\em process()} when the
        currently processed file is at end-of-file. This is indicated
        by the {\em lexer()} return value {\em l\_eof}.

        {\em popfile()} closes the file pointer associated with the processed
        file and decreases the filestack pointer {\em filesp}. See {\em
        pushfile()} for a description of the filestack.

        If the processed file is a file which is included by an {\em \#include}
        directive, then a `\#' character is written to the output file. This
        signals the next pass of {\em icmake}, the compiler, that an included
        file ends. If the filestack is empty; i.e., when the processed file is
        the main file, no `\#' is written to the output file.
