For some reason, Apple chose to use a different numbering system for
Gestalt than they used for SysEnvirons.  Just to confuse us, I guess!
Here are the machine types that Gestalt returns:

#define gestaltClassic                          1
#define gestaltMacXL                            2
#define gestaltMac512KE                         3
#define gestaltMacPlus                          4
#define gestaltMacSE                            5
#define gestaltMacII                            6
#define gestaltMacIIx                           7
#define gestaltMacIIcx                          8
#define gestaltMacSE030                         9
#define gestaltPortable                         10
#define gestaltMacIIci                          11
#define gestaltMacIIfx                          13
#define gestaltMacClassic                       17
#define gestaltMacIIsi                          18
#define gestaltMacLC                            19

Here are the machine types that SysEnvirons returns:

enum {envMac = -1};
enum {envXL = -2};
enum {envMachUnknown = 0};
enum {env512KE = 1};
enum {envMacPlus = 2};
enum {envSE = 3};
enum {envMacII = 4};
enum {envMacIIx = 5};
enum {envMacIIcx = 6};
enum {envSE30 = 7};
enum {envPortable = 8};
enum {envMacIIci = 9};
enum {envMacIIfx = 11};
