IMHO the following should be efficient, calling the function only once,
near the time of the first use (if not, should be fixed):
foreign import aConstant :: Int
------------------------------------
#include <header.h>
int aConstant (void)
{
return A_CONSTANT;
}
A tool could be helpful in massive generating such functions...
