[pure-lang-users] C macros

[Eddie R. <er...@bm...>]

How do I import constants defined as macros in C?

Example:
GSL has M_EULER defined as 

#ifndef M_EULER
#define M_EULER    0.57721566490153286060651209008      /* Euler
constant */
#endif

I want to be able to access that from gsl.pure.

using "lib.libgsl";

extern ???
