  43 /* 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.
