The symbols for function names are there, just not the DWARF 
debug info, if you want to step through the corresponding source 
line by line.

Assuming you want to use the debug version, you may be better off 
using ldc, which comes with debug versions of druntime and phobos 
and the -link-debuglib option, which will use those instead.  dmd 
and ldc also have the -defaultlib= and -debuglib= options, from 
which you can specify your own or a debug build of the standard 
library, with -debuglib= used if you compile with -g.
