It means the application can access 2^32 bits of memory i.e 4gigs.And
this means a 64 bit application needs a 64 bit kernel atleast, which
will run on a 64 bit processor. Aliter a 32 bit application can run on
top of either 32 or 64 bit kernel. And a 32 bit kernel can run atop a
32 bit processor or 64 but processor.

No such restriction for C in windows. It is still 4 bytes.
