Summary: unable to serialize Infinity or NaN on ARM using marshal

Initial Comment:
forwarded from http://bugs.debian.org/434905, patch by
Aurelien Jarno.

python2.5 is unable to serialize a floating point variable which equals Infinity or NaN on ARM using marshal.

The problem is that python2.5 wants to manage the floating points in memory by itself, and assume that they are only little and big endian IEEE formats. Otherwise it fallback to a generic code, which does not handle NaN or Infinity.

The attached patched fixed that by adding mixed-endian IEEE format, as it can be found on ARM old-ABI.
