This uses some macro magic:

  #ifdef GCRY_USE_VISIBILITY
  # define MARK_VISIBLE(name) \
      extern __typeof__ (_##name) name __attribute__ ((visibility("default")));
  # define MARK_VISIBLEX(name) \
      extern __typeof__ (name) name __attribute__ ((visibility("default")));
  #else
  # define MARK_VISIBLE(name) /* */
  # define MARK_VISIBLEX(name) /* */
  #endif
  [...]
  MARK_VISIBLE (gcry_mpi_powm)


FWIW, Libgcrypt 1.6 should be easier to read in this regard.


Salam-Shalom,
