Dear Mike,
I am sorry to contradict what you say, but what I get is
sizeof(int) == sizeof(long) == 4
compiling on Windows 7 (64 bits) with Visual Studio 2008. The data type
size is the same when I compile a 64-bit executable and a 32-bit
executable.
In order to have an 8-byte variable I must use long long, in fact I get
sizeof(long long) == 8
But maybe this is compiler dependent (I'm not an expert of Visual Studio,
I usually work on Linux).

That is ONLY valid on 32 bit windows. On 64 bit windows long is 8 bytes
in length. The use of "long" should just be banned, IMHO.

(ie just inverting the order from INT - LONG - LONG LONG to LONG LONG -
LONG - INT.) In this way ssize_t is of type long and there is no
conflict with ImageMagick. And I think there is no real change in HDF5
too, since sizeof(int)==sizeof(long).
