88    2002, GCC does record the effect of #line directives in the source
89    line info, but not in macro info.  This means that GDB's symtabs
97    suitable for ordinary non-macro line number info.

111    numbers", and has a data structure called a "line map" that can map
112    logical line numbers onto actual source filenames and line numbers,
114    particular logical line number.  Basically, this means you can pass
115    around a single line number and some kind of "compilation unit"
