A filename, whose mapping to file access is defined by the implementation.

X3J11 tried to identify a minimal "portable filename" subset for use in
applications as header file names.  There almost wasn't any common subset.
I think we figured out that five monocase alphabetics followed by ".h"
would be all that could be guaranteed across all the C implementation
environments we knew of, and there were problematic aspects of even such
a minimal guarantee.  That hardly seemed worth the trouble.
