And what's the problem? If the user has "a.cpp" and include path for it
includes the "a.cpp"'s directory, and the generated file will be found 
if it's generated to that dir. We generate it to different dir, so we 
need to make sure it will be picked up properly.

One variant will have include paths tweaked so that include one version 
of the header. Another variant will include another version.

However, if "a.cpp" includes a_parser.h via <> and "." is not in the 
search path, we won't do anything about this file.

I mean the directory where including file lives.
