/* The e500 ABI says that either long doubles are 128 bits, or if
44
   implemented in any other size, the compiler/linker should error out.
45
   We have no emulation libraries for 128 bit long doubles, and I hate
46
   the dozens of failures on the regression suite.  So I'm breaking ABI
47
   specifications, until I properly fix the emulation.

   Enable these later.
