I suspect that the following bug report explains why
the float-format tests fail under pretty much everything except
GNU/Linux.
For what it's worth, the fix hasn't been committed yet into
Gnulib, but I assume it will be soon.

Subject: byteswap test failure
Hi Oskar,
A few weeks ago, I contributed a unit test for the 'byteswap' module.
And it fails on MacOS X. bswap_32(0xDEADBEEF) = 0xEFBE00DE. Do you agree
to this proposed patch?
