Binding problem

[Poul-Erik Andreasen <poulerik@pea.dk>]

Hey

I am trying to write a binding to the FANN libery.

There i have a function who look like this

  FANN_EXTERNAL fann_type *FANN_API fann_run(struct fann * ann, 
fann_type * input)


The problem is the fann_type * input. Orcording to the manual this
can be ether a integer a float or a double, depending on whitch
headerfile there have been included, this is also visible in the c-code
where som of the execution is controlled by some ifdef statement.

I want to split i up in 3 function but how can i from ada simulate that 
one or another Headerfile are included.
