In this case, trying to write the file will answer "a/a.c: E212 Cannot
open file for writing", showing that there is *no* path to the file. But
after creating a subdirectory ./a in the current directory,
expand('%:p') gets a sensible value, and the write (if attempted) succeeds.

On Unix you might try
:exe '!mkdir -pv' expand('%:h')
:w
if you really want to save the file under that name. (Of course it will
fail if you don't have the necessary directory-creation permissions.)
