I'm trying to compile iozone3-196 on solaris9 with 64bit option and I get
following error:

% make Solaris8-64

Building iozone for Solaris8-64

cc -fast -xtarget=generic64 -v -c -Dunix -DHAVE_ANSIC_C -DASYNC_IO \
        -D__LP64__ -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 \
        -DNAME='"Solaris8-64"' -Dsolaris -DHAVE_PREAD \
        iozone.c -o iozone_solaris8-64.o
compiler(iropt) error:  unmatched succ and last triple in b[31]
 
cc: iropt failed for iozone.c
*** Error code 2
make: Fatal error: Command failed for target `iozone_solaris8-64.o'

I don't have problem with "make Solaris" or "make Solaris7gcc" to
build a 32bit mode version.

Thanks,
