Yes, in addition to CLP, CBC, CGL, and their cosrrespoding OSI
interface, there's a C library called CoinMP, that will be used
in OpenOffice's calc.

Actually, I added them for CLP and we had a knob to use them there but
I never understood how to make any use of it. I eventually got tired
of having port bumps everytime GLPK was updated and killed the knob.
I recall pretty much every header that you removed was required, but
the thing with COIN is that it's mostly libraries so you usually only
need this if you are a programmer and want to use the specific functionality in OSI.
