Hi hackers!

Here is gist cube penaly patch v5.
Changes:
1. union version of pack_float() is used, without warings and with
minimum asm commands emitted
2. test for __STDC_IEC_559__ is added, this is a standard way of C99
to determine float compliance with IEEE754. ANSI-only compiler+libs,
along with non-IEEE-float-systems, will fallback to pre-patch
behavior.

Best regards, Andrey Borodin.
