In my environments, I setup the compiler and CFLAGS before calling configure w/ the right information to build 32, or 64 bit binaries. Having configure try to guess and pass in additional values is a royal pain. Passing in --libdir=/usr/lib64 (or equiv) is really the right answer. There shouldn't be any MARK64 or similar checks in configure or other components. If they care about type sizes, then they should use the size types, i.e. uint32 instead of "long", or they should check sizes using the autoconf variables and adjust things based on that.
(One rare example. There is a mips64 target that comes back 32-bit in all of the tests. If the system checks for "64" in the arch name it WILL do the wrong thing. It needs to look at type sizes to determine what to do. Most software gets this right.) --Mark Ralf S.
