np.float128 does not always exist

When compiling the latest SVN (62197) of GRASS7 trunk I run into following error (first among the error list, mostly in the temporal dir):

Traceback (most recent call last):

Here I am running Python 2.7.3 with numpy 1.9.0.

Here ​http://stackoverflow.com/questions/9062562/what-is-the-internal-precision-of-numpy-float128 it says that is is related to the architecture. In my case I am on a 32 bit system.

Changing from np.float128() to np.longdouble() (which exists on my system) should solve the problem.

Right, I didn't thought about it!

Now should be fix in r62206. Moreover I've disconnected (r62205) and isolate the ctypes part of pygrass from the rest, this should make the whole pygrass more stable (I hope).

Is this ticket still valid?
