* the compiler output (error messages, warnings, etc.);
No error messages
* There is no DW_MACRO_start_file for the "base" source file
submitted to the compiler for compilation.
According to the document "DWARF Debugging Information Format",
Version 3 November 12, 2003 (Draft 9), see
6.3.2 Base Source Entries,
"In addition to producing a matched pair of DW_MACRO_start_file
and DW_MACRO_end_file entries for each inclusion directive
actually processed during compilation, A PRODUCER SHOULD GENERATE
SUCH A MATCHED PAIR ALSO FOR THE "BASE" SOURCE FILE SUBMITTED TO
THE COMPILER FOR COMPILATION."
But readelf does not show a DW_MACRO_start_file for the "base"
source file.
* NOTE: gcc-3.2.2 GENERATED the DW_MACRO_start_file entry for the
"base" source file.
