Detecting 64bit vs. 32bit Linux

[Michael Yanowitz]

  The one thing I observed (just an observation) is that:
a) on 32-bit machines:
    sizeof(int)  = 32
    sizeof(long) = 32
b) on 64-bit machines:
    sizeof(int)  = 32
    sizeof(long) = 64

    This in C and Python.

Thanks in advance:
Michael Yanowitz

The standard C way would be to check sizeof(void *).
