There are many ways of doing it, but they all tend to suffer from the
problem of identifying which headers are actually needed based on
the contents of a file, and also figuring out where to put the extra
#include if there are complex #ifdefs.

For reference, see below for the naive pattern matching I tried.
This is obviously incomplete and partially wrong.
