If you looked in data-conv.h, you would find

  #if SIZEOF_SHORT == 2
  #define TWO_BYTE_INT short
  #elif SIZEOF_INT == 2
  #define TWO_BYTE_INT int
  #else
  #error "No 2 byte integer type found!"
  #endif

  #if SIZEOF_INT == 4
  #define FOUR_BYTE_INT int
  #elif SIZEOF_LONG == 4
  #define FOUR_BYTE_INT long
  #else
  #error "No 4 byte integer type found!"
  #endif

It looks like you are using gcc on an Intel (compatible) system.  If
so, then I would expect SIZEOF_SHORT == 2 and SIZEOF_INT == 4.  The
configure script checks for this are done using standard autoconf
tests:

  ### How big are ints and how are they oriented?  These could probably
  ### be eliminated in favor of run-time checks.

  AC_CHECK_SIZEOF(short, 2)
  AC_CHECK_SIZEOF(int, 4)
  AC_CHECK_SIZEOF(long, 4)
  AC_CHECK_SIZEOF(long long, 8)

So, why doesn't the configure script work correctly for you?
