I don't think so, the ABI says 8 in both cases.
Note that bootstrap doesn't fail on SPARC/Solaris 2.[56] and (presumably)
SPARC/Linux, which have HOST_WIDE_INT == 32, whereas SPARC/Solaris 7+ have
HOST_WIDE_INT == 64. All are 32-bit compilers.
Bootstrap doesn't fail on SPARC64/Solaris 7+ either, for which the ABI says 16
for the alignment in both cases. They are 64-bit compilers.
