The treatment of long doubles on HPUX and Linux is different. Long
doubles are 128-bit IEEE format on HPUX. They are 64-bit IEEE format
on Linux (i.e., same as double). Arguments larger than 64 bits are
passed by indirect reference. Thus, the 128-bit format is always passed
by reference. Smaller arguments are passed by value.
