Is there a mechanism I have not yet found that would allow me to use a DEFINE to control whether hints are on or off in a particular unit? I am doing new work on a base form and am getting hints on unused private symbols. I realize that I could solve it manually, but prefer something which would take care of itself, so I don't allow those hints in the code pushed to SCM.

Is there a mechanism I have not yet found that would allow me to use a DEFINE to control whether hints are on or off in a particular unit? I am doing new work on a base form and am getting hints on unused private symbols. I realize that I could solve it manually, but prefer something which would take care of itself, so I don't allow those hints in the code pushed to SCM.

For clarity, I was hoping to something like this:
{$IFNDEF SHOWHINTS} // defined in the project
{$HINTS OFF}
{$ENDIF}
