It'd be nice if someone added support for use-64-bit-pointers-if-available to Autoconf, much as AC_SYS_LARGEFILE added support for 64-bit off_t on platforms that supported that. Nobody has done it yet, as far as I know. You can look at AC_SYS_LARGEFILE for some ideas about how to do it. > I tried to specify '-m64' as a build flag but I believe this isn't > the right way to go since (a) this makes my configuration > compiler-dependent; (b) 64-bit build is enforced even on platforms > that do not support it. Right on both counts.
