r36854 was against your first problem, the other problems should also be fixed.
My compilers didn't catch that because I don't have this arch to test.
I've added a whole bunch of new float converters.

A 2nd problem on Sparc64 was tracked at TT #364,
And I thought that this is a more general problem, that cannot be solved easily.
But your were saying it worked before fine. Do you relax ptr alignment ?
-xmemalign=4i for example?

$ svn log src/packfile/pf_items.c | head -n 60

TT #308. cvt_num8_num12 tested ok, so cheap compiler casts work ok.
- fixed a ptr problem.

TT #308: immediate fix for 64bit big-endian
- add two missing functions for 64bit big-endian
- change endianize transformers: first endianize, then convert
- describe the three floatformats in detail
- start with prototypes for 16->8, 12-16, 16->12
  and the simplier casting versions for 8->16, 8->12
- disable target conversions for non-matching targets (smaller obj size)

[src] Fixed compiler warnings about memory overflows during memcpy().  I'm not
sure these are correct, but they don't warn and all tests pass.  If they're
still wrong, that's because the code assumes too much.
