What we'd really like is something like:

/* foo.h */
#ifndef _FOO_H
#define _FOO_H
#define _FILE_REF __fileref_foo_h


#undef _FILE_REF
#endif /* _FOO_H */

... and have an automatically generated library (.a file) with all these
strings that could be pulled in as necessary -- but only one instance of
each. However, doing this without compiler support seems ugly in the
