  The poster didn't ask about 32 bit longs, he asked about 32 bit ints.
There is a book called _The C Programming Language_ which will explain
the diference.

  Intel has several manuals which explain the diference in the way 32
bit ints work, as opposed to longs on a 286 compiler which are
implemented as two 16 bit ints and about 300% overhead.

  To sum it up in beginners language: 286 compilers don't use 32 bit
arithmetic for anything, they fake it with 16 bit arithmetic and run a
lot slower.
