FYI, here's a summary of Google search result counts:
__INTMAX_TYPE__ - 3,160 hits vs intmax_t - 53,200 (1 to 16.8)
__UINTMAX_TYPE__ - 3,190 uintmax_t - 47,100 (1 : 14.8)
__PTRDIFF_TYPE__ - 10,900 ptrdiff_t - 106,000 (1 : 9.7)
__INTPTR_TYPE__ - 228 intptr_t - 48,900 (1 : 214.5)
__SIZE_TYPE__ - 35,800 size_t - 3,120,000 (1 : 87.2)
__WCHAR_TYPE__ - 10,500 wchar_t - 361,000 (1 : 34.4)
__WINT_TYPE__ - 7,810 wint_t - 47,700 (1 : 6.0)
I included the results for the standard type definitions, too, to give a
rough sense of proportion for each of the types.
