have a symtab for a source file that doesn't appear in the
macro table. For example, at the moment, Dwarf doesn't have
any way in the .debug_macinfo section to describe the effect
of #line directives, so if you debug a YACC parser you'll get
a macro table which only mentions the .c files generated by
YACC, but symtabs that mention the .y files consumed by YACC.
