I believe that can be done with the 'new' syntax as...
alias BCRYPT_HANDLE = HANDLE;
alias BCRYPT_ALG_HANDLE = HANDLE;
alias BCRYPT_KEY_HANDLE = HANDLE;
alias BCRYPT_HASH_HANDLE = HANDLE; 
alias BCRYPT_SECRET_HANDLE = HANDLE;
... which despite its verbosity, I actually prefer.

One of them needs to go, and I prefer that the 'old' syntax go and the '='
syntax remains.

What's the issue number for this?
