[Bug debug/13276] New: missing debug information (dwarf2) for global variable

["sdouglass at arm dot com" <gcc-bugzilla at gcc dot gnu dot org>]

When I compile the following with gcc 3.3.2 (configured with --with-dwarf2) in
C++ mode no debug information is produced for 'var' -- there is no
DW_TAG_variable entry.  When compiled in C mode the debug info is present.

struct T { int a, b, c; };
extern struct T var;
struct T var;

> gcc -v
