    Yes, these are guaranteed. In C++11, see §7.1.6.2[dcl.type.simple]/table 10, which lists all of the simple type specifiers (and combinations thereof) and what they mean. For example, the table includes the following:

    unsigned      => unsigned int
unsigned int  => unsigned int

signed        => int
signed int    => int
int           => int

    C11 has a similar mapping in §6.7.2/2 (it’s formatted differently, but otherwise it specifies the same groups of equivalent combinations, at least for all of the types common to C and C++).
