We have new options -fno-eliminate-unused-debug-types and 
-fno-eliminate-unused-debug-symbols.  The default is to not emit 
type/symbol info for unused types and symbols, and these options can be 
used to turn this off.  However, this makes no difference for this 
testcase with gcc-3.5.  I would expect to get debug info with the 
options, and without the options, it may or may not be there.

Using dwarf2 debug output, I get no info for the type my_struct and the 
symbol foo.  Using stabs debug output, I get no info for the symbol foo, 
but I do get info for the type my_struct.
