Comment (by Roland Haas):

Also, looking at your description once more. Since the conflict is with an error_t typedef in you glibc’s error_t.h file (used in errno.h it seems) can you let me know which OS you are trying this on?

We can certainly include patch `h5_error.h` in the way you fixed in future releases.
