In my opinion, this type of change is not acceptable.
If VIM is to be targetted for 32-bit platforms, it should have the option to
run with 32-bit wide types on those platforms for optimal performance.
64-bit wide types on 32-bit platforms cause 64-bit arithmetic emulation
to be performed on ALL integer-based calculations, impacting the speed
of such calculations, be it in-script variable access, loop control, etc.
The typedef should look like this:
#if sizeof(size_t) > 4 /* ANSI C only. need to change to cross-standard
64-bit test */
typedef int64_t varnumber_T;
#else
#if SIZEOF_INT<= 3 /* use long if int is smaller than 32 bits */
typedef long varnumber_T;
#else
typedef int varnumber_T;
#endif
#endif
Use of size_t is the best way in ANSI C to know the width of the system
bus as size_t must be able to reflect the size of the largest possible
addressable memory object (as returned by "malloc()").
