Re: [ros-dev] [ros-diffs] [greatlrd] 37343: Bugfix : Do not link to LPDDRAWI_DIRECTDRAW_INT->lpLink when we do not have any LPDDRAWI_DIRECTDRAW_INT->lpLcl

[gedmurphy]

Is it not time to start getting rid of IsBadWritePtr and friends?
I don't see a good reason for these in our own code, especially when we can just use
SEH directly.
