* config/h8300/h8300.h (TARGET_H8300H, TARGET_H8300S): Make sure
UNITS_PER_WORD and BITS_PER_WORD are compile time constants when
compiling libgcc2.
* config/mips/mips.h (TARGET_64BIT): Likewise.
* config/rs6000/rs6000.h (TARGET_POWERPC64): Likewise.
* libgcc2.c: Use {,U}{HW,W,DW}type and DWunion everywhere instead
of {SI,DI}type and DIunion. Define these types to QI/HI modes on
dsps. Give routines proper names if SI/DI modes are not used.
* longlong.h: Use DWunion instead of DIunion.
