Library files shouldn't be using gcc internal headers.  It is a 
historical error that some libobjc files do.  We shouldn't compound the 
error by adding more.

Is there some way to fix this without using gcc internal headers?

It looks like the proper fix is including some header files from 
boehm-gc/include/private which define modWORDSZ and divWORDSZ.  I didn't 
look at how one does that.
