It's more an issue of the standard ABI for the particular OS/processor
combination.  I don't remember offhand which it has been an issue for in
the past (the last time the issue came up for me was a long time ago),
although I want to say Alpha was one of them.

There's also the issue of -- if you have cairo callbacks that can throw
C++ exceptions -- you will need to be _very_ careful in structuring
cairo itself so that throwing an exception will not cause a resource
leak, because any cleanup bits in the C call stack will get ignored as
the stack is unwound.  c.f. the gtkmm FAQ.
