I'm using the most recent 1.1.1 version. I only installed it to test the 
pvfs2 setup since I expected the ROMIO version to be the most recent. 
Looking at ad_pvfs2.h it seems that the patch you attached seems to be 
already included:

#ifdef PVFS2_VERSION_MAJOR
#include "pvfs2-compat.h"
#endif

void ADIOI_PVFS2_Open(ADIO_File fd, int *error_code);
void ADIOI_PVFS2_Close(ADIO_File fd, int *error_code);

Thanks,
