This logic is obviously wrong:

predef/include/boost/predef/architecture/riscv.h

Lines 29 to 41 in 614546d

#if defined(__riscv)
# undef BOOST_ARCH_RISCV
# define BOOST_ARCH_RISCV BOOST_VERSION_NUMBER_AVAILABLE
#endif
#if BOOST_ARCH_RISCV
# define BOOST_ARCH_RISCV_AVAILABLE
#endif
#if BOOST_ARCH_RISCV
# undef BOOST_ARCH_WORD_BITS_32
# define BOOST_ARCH_WORD_BITS_32 BOOST_VERSION_NUMBER_AVAILABLE
#endif

IIUC __riscv_xlen can be used to detect correct word bitwidth.
