Comment (by yawning):

 Replying to [comment:1 nickm]:
 > Can you tell whether Solaris10 has a signbit() function and we are
 somehow not linking against the library that has it, or whether Solaris10
 is missing signbit and we'll have to define our own?

 As far as I can tell from searching the intertubes, certain versions of
 GCC on Slowlaris ship a version of `signbit()` that causes aliasing
 warnings.  That said, per the man page, including `math.h` should be
 enough (since it's by definition macro), and we also link with the math
 library...

 What version of GCC are you using?
