------- Comment #9 from howarth at nitro dot med dot uc dot edu 2009-08-28 15:31 ------- Back to the issue of configure not properly detecting the target as x86_64-apple-darwin10 but grabbing i386-apple-darwin10 instead, one possible fix would be to have configure use 'sysctl -n hw.cpu64bit_capable' to test on darwin10 if the target is compiling x86_64 code. Configure can't blindly assume x86_64 on darwin10 because the first generation Intel Macs with non-EMT64 capable processors will generate 32-bit code from the system gcc.
