This patch adds D language support to GCC itself.
---
gcc/ChangeLog
* config/rs6000/rs6000.c (rs6000_output_function_epilogue):
Support GNU D by using 0 as the language type.
* dwarf2out.c (is_dlang): New function.
(gen_compile_unit_die): Use DW_LANG_D for D.
(declare_in_namespace): Return module die for D, instead of adding
extra declarations into the namespace.
(gen_namespace_die): Generate DW_TAG_module for D.
(gen_decl_die, dwarf2out_decl): Handle CONST_DECLSs for D.
* gcc.c (default_compilers): Add entries for ".d", ".dd" and ".di".
