Many OSes support both 32 and 64 bit executables. To know which type your executable is, you should also print sizeof(void*) which will always be 8 in a 64 bit executable and 4 in a 32 bit executable. If you add a sizeof(void*) to the above I wouldn't be surprised if you find you have a 32 bit executable and need a command line option to create a 64 bit executable. Its like this on Solaris running on Sparc.
