Hmm, looking at the .c header, the function is not even

it is not used, and in this case turning macros into

in the binding (I have simply commented out the functions in
my repo, as
they don't seem to be used). But its worth noting.
If a macro is turned into a function it needs to have an
implementation.
when marcos are turned into functions they introduce new
symbols. it's a
pity, but in that case you have to link to deimos. so deimos
will become
a wrapper rather than a binding.
I compile the deimos bindings along with my own code, so that's
not a problem.
The function in question was actually proto'd as an extern, so it
was expecting another library to resolve it. The original C
header did not even define the function (whereas the binding
does, but as an extern dependency) so it would appear that the
macro was/is never used, otherwise using the .c header would
introduce an undefined function. I guess macros can introduce
undefined symbols
as long as they are never used, but the same is only true for .d
bindings if they are introduced as templates like David said.
