A "normal" PC has a 64 bit CPU, only antiques have old 32 bit processors, so there is no "user coverage" to be gained. Since 64 bit builds with the good instruction sets are necessary, 32 bit builds are costly (due the complication of additional toolchains and libraries) but useless except for special needs. Moreover, short numerical types are likely to cripple 32 bit software that formally "works", for example by limiting file size to 2 or 4 GB.
