No doubt about that. The problem is, this was installed without mention in the
ChangeLog so looks quite unintentional. If this is intentional, you should fix
the ChangeLog.

Please read comment #5.

See utils.c:create_var_decl_1
/* Ada doesn't feature Fortran-like COMMON variables so we shouldn't
try to fiddle with DECL_COMMON. However, on platforms that don't
support global BSS sections, uninitialized global variables would
go in DATA instead, thus increasing the size of the executable. */
if (!flag_no_common
&& TREE_CODE (var_decl) == VAR_DECL
&& !have_global_bss_p ())
DECL_COMMON (var_decl) = 1;
