Hi,

It looks like for low-level programming following macro could be really useful:

BOOST_ARCH_BITS_64 BOOST_ARCH_BITS_32 BOOST_ARCH_BITS_16 ?

Predef also missing BOOST_ARCH_ARM_64, BOOST_ARCH_PPC_64.

Boost.DLL really needs those macro for detecting bit's dependent elf/macho/pe structures layout. Is it possible to add them?

Maybe.. If I knew what they are supposed to mean? I.e. can you explain what you mean by "bits dependent structures layout"?

BOOST_ARCH_BITS_* is mostly a macro for sizeof(void*). In other words: * define BOOST_ARCH_BITS_64 to 1 on BOOST_ARCH_x86_64, BOOST_ARCH_ARM_64, BOOST_ARCH_PPC_64 * define BOOST_ARCH_BITS_32 to 1 on all other archs. -- Best regards, Antony Polukhin
