I've changed `configure' so that 64-bit mode is no longer disabled by default for Mac OS X builds. The build now uses the default mode of the compiler, which is typically 64-bit mode for Mac OS X 10.6 and 10.7.
To get a 32-bit mode build when your compiler's default is 64-bit mode, configure with `--disable-mac64'. I know of no particular benefit to 64-bit mode for most programs, which use much less than 4GB of memory, and 32-bit mode is usually 10% faster (or as much as 30% faster for GC-intensive tasks). Since Racket now works fine for 64-bit Mac OS X, however, it makes sense to switch the default build mode to the system-wide default. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
