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.
In the long run, we should extend the Dwarf macro info
representation to handle #line directives, and get GCC to
emit it.
For the time being, though, we'll just treat these as
occurring at the end of the main source file. */
