Check _LONGLONG_TYPE as well, to define 'word64', to make it
work on Solaris 10 x86_64.
Can't assume all x86_64 share the same assembler syntax.
For now disabled assembler for x86_64 and Solaris.
remove FIX_GCC_LINKING_PROBLEM and -DDEFINE_CXA_PURE_VIRTUAL
replace echo in configure.in with AC_MSG_WARN/AC_MSG_ERROR
don't set -DUSE_MYSYS_NEW for gcc 2.95
set $USE_MYSYS_NEW even if CXX is g++
