intptr_t and uintptr_t are defined in C99 and appear in some C code (Scintilla being one prominent example). The "Data Type Compatibility" table on this page https://dlang.org/spec/interfaceToC.html#data_type_compat should include those types. They are defined in core.stdc.stdint. They might not be common, but in the current form, that page leaves the impression that they're not even available.
