Hi.

This is something I've wanted for awhile.

bash$ g++ -g -Og hello.cc -o hello
bash$ gdb hello
(gdb) start
(gdb) info source
Current source file is hello.cc
Compilation directory is /home/dje
Located in /home/dje/hello.cc
Contains 8 lines.
Source language is c++.
Producer is GNU C++ 4.8.2 -mtune=generic -march=x86-64 -g -Og -fstack-protector.
Compiled with DWARF 2 debugging format.
Does not include preprocessor macro info.
(gdb)

Regression tested on amd64-linux.
