(sorry for the previous empty mail)
I don't think it is reliable. The manpage for dirname says (emphasis mine):
These functions may return pointers to statically allocated memory
which may be overwritten by subsequent calls. Alternatively, they may
return a pointer to some part of path, so that *the string referred to
by path should not be modified or freed* until the pointer returned by
the function is no longer required.
