Do not use the #line directive when using the debug facility under
QuickC or while using CodeView.

The #line directive tells the preprocessor to change the compiler's
internally stored line number and filename to a given line number and
filename. The compiler uses the line number and filename to refer to
errors that it finds during compilation. The line number normally
refers to the current input line, and the filename refers to the
current input file. The line number is incremented after each line is
processed.

If you change the line number, the compiler ignores the previous
values and continues processing with the new values. Therefore, if you
debug or use CodeView, the trace does not match up to your source
code.
