I would agree with Joel, once a debugger adds the more permissive syntax
it seems ok to simply allow it for those who want it.
Plus the down side of adding the new DW_LANG value is that older
debugger versions will no longer work correctly with a new compiler. It
seems like the tradeoff of disallowing support for the more permissive
new syntax on old Ada95 code is far outweighed by the impact when a user
upgrades the compiler and then an older debugger no longer works like it
used to.
