Ah, I hadn't realised that this was an issue.
Is there a define somewhere (or could we add one) that would allow
those users who are happy to recompile to update to a new interface?
What I have in mind is to have
---------------------------------
// the new function
int function_e(...)
{
}
#ifdef MAINTAIN_BINARY_COMPATIBILITY
// keep the old function
#define function function_e
#else
// add the new function
double function(...)
{
EVAL_RESULT(function_e(order, qq, zz, &result));
}
#endif
This would also make it easy to move to v2.0.
I would be happy to do the work involved although it would need checking
on Linux.
