[erlang-bugs] Problem compiling --enable-darwin-64bit on Mac OS X

[Bob Ippolito]

Using the source from otp_src_R12B-1.tar.gz I'm unable to compile a
64-bit Darwin build.

$ sw_vers
ProductName:	Mac OS X
ProductVersion:	10.5.1
BuildVersion:	9B18
$ cc --version
i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5465)

$ ./configure --enable-darwin-64bit --prefix=/mochi
