Yes, this is a problem.  And, yes, it needs to be taken care of in a designed,
methodical manner -- the spi.h header should only need a few things (I, like
you, have not done any SPI development yet to see what really _is_ needed....).

Yes, most certainly.  Can someone who has actual SPI experience look at this?

I'll have to admit to taking the easy way out a little in  my RPM solution --
but, it's only there so that an advertised development interface can be
actually used.  Once a thorough look is taken at the whole header mess for SPI,
I still won't have to change anything, which is good both for me and for RPM
users, as I really don't keep track of every header file dependency change --
thus, RPM releases won't happen (again, as 7.0-1 was in error in this regard)
with broken header deps, requiring a bugfix package.

If no one else is forthcoming with a solution to this problem, I'll take a look
at it (possibly during the development cycle for 7.1 after the 7.0.x series has
stabilized, when the RPM cycle is at idle).
