We need to kill C syntax for declaring function types

It seems this little patch of yours fixes something like 4 different bug reports present in Bugzilla :-)

I suggest to add to the D docs a note that lists all the purposes of the -d command line switch, including accepting C function pointers.

So the -cstyle command line switch may be replaced by the -d. Regarding bug 4580, is it possible to use the -d switch to deprecate (and re-enable when it is used) C-style array declarations too? (Bug 4580 talks about two extra warnings too, they too may be tied to the -d switch, but they are less important).

Bye and thank you,
