Unfortunately since the OSGB36 datum is not defined in PROJ.4 < 4.5.0,
the library throws an error if you attempt to use this parameter with
older versions - so I don't really know what to do about this :(
Not sure about SRID 4277 - I can't say that I've ever used it for any of
the OS data I've come across.
