If itemsize is a power of two use that as the required alignment up to the maximum provided by the platform. Power of two sizes may be accessed via larger moves than bytes. Non-power of two sizes are accessed bytewise and can thus always be considered aligned. Closes numpygh-5293
malloc only provides 8byte alignment and is sufficient to load complex on x86 platforms. This fixes the f2py alignment failures with complex types on win32 or on linux32 with -malign-double

OK remove 'fixup'. |
|
looks ok, I'll probably backport some more minor stuff this weekend and then we can do a 1.9.2 |
|
note I don't know when I'll finish the other fix, I tend to look at the duplication in raw_assign* get anoyed and stop, and I'm also to lazy to actually try to homogenize it ;) |
