To solve the apr.h issue you can use diff to build a merged version of apr.h after performing separate 32-bit and 64-bit builds (diff -D some-symbol 32-bit/apr.h 64-bit/apr.h >merged/apr.h", where some-symbol is whatever the compiler provides to select between 32-bit and 64-bit). I don't think anybody has spelled out explicitly how to run the apr and apr-util builds and merge all necessary headers and so forth (not that it is complicated, but it would be useful as a FAQ...). (In addition to the apr.h issues you outline, some of the APU_HAVE_foo in apu.h could differ between 32-bit and 64-bit as well.) (sticking with just plain Leopard for now ;) )
