PSR1 lists this as a 'SHOULD', not a 'MUST'.
The purpose of this rule, as I understand it, is that 'reusable' stuff
should be reusable by including the file that define it, and shouldn't
force some action to be performed. Also, that includes that 'do
something' may be needed in multiple places, and if they define stuff,
they can't be multiply included.
If the define()s are purely for internal usage, and the file has no
possible reason for wanting to be included twice, then we may fall
within a valid exception to PSR-1.
To be strictly meeting it, the definitions (define() etc) should be
factored out into an include file that is required_once.
