The error started out as an erroneous test of using v16 API via
source code. (See bug 1264). It was implemented as:
#include "hdf5.h"
#define H5_USE_16_API
That was incorrect and generated warnings in Linux but error in AIX
for redefining macro H5_USE_16_API.
I corrected it yesterday to pass AIX by moving H5_USE_16_API up as:
#define H5_USE_16_API
#include "hdf5.h"
This is the proper way to turn on v16API and it passes all normal
tests. I knew it would not work if somehow v16API is disabled
but hoping it can be fixed later. Well, it broke last night
under --disable-deprecated-symbols.
Removed the #define H5_USE_16_API and let Raymond fix it after
the release.
