Dear All,

Thanks Konstantin Olchanski for providing me a hint. The file can be opened now after I 
changed the line: 

file->gzfile = gzopen(file_name, "rb");

in function ma_open() in mana.c to the followings: 

INT fd = open(file_name, O_RDONLY | O_LARGEFILE);
if (fd <= 0)
   return NULL;

file->gzfile = gzdopen(fd, "rb");

No modifications to the Makefile is needed in this case.

Best Regards,
Jimmy
