While "#if USE_FOO" checks for the value of the variable USE_FOO,
"#ifdef" checks whether USE_FOO is defined or not.
It means, if we had something like: #define USE_FOO 0, we would have:
#if USE_FOO
/* Any code in here would NOT be compiled */
#endif
#ifdef USE_FOO
/* Any code in here would be compiled */
#endif
No problem was faced on spice-gtk till now because either USE_FOO is not
defined or defined as 1, but let's try to have it standardized.
