[cfe-dev] automatic include

[VanDung To]

Thanks for the quick response.

I'm not looking for a compile time option (-include -I).   In the
environment I'm looking at, it is very awkward to force the user to specify
the include file every time. Is there a way for clang to do this without
using the compile time option?   I'm willing to modify/hack some code.

Sincerely,
