I am porting gdb 7.6.2 and I would like to try dwarf4 support.
To this purpose I want to compile gcc 4.9.0 and the question
arises how to enable dwarf4 support.  I would also like to build
a gcc version with full dwarf2 debug support so I can step into
the compiler code with old gdb port.  I am aware that dwarf4
support has been disabled in previous compiler ports.

Regards,
Juan M. Guerrero
