Hi Garrison,

The way I handle this is to use PreprocessorOpts::addRemappedFile to
set up a mapping from a source code "file" name to the memory buffer
(which is really a dummy file name that shows up in diagnostics etc).
I then add that name to the input list.  You can see my source
code here:

(in particular lines 815-816 and 818)

Thanks,
