Subject: Basic: make `int_least64_t` and `int_fast64_t` match on Darwin
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d569b56d4d26d45cee1d65b868318cba15358fc6;p=clang

Basic: make `int_least64_t` and `int_fast64_t` match on Darwin

The Darwin targets use `int64_t` and `uint64_t` to define the `int_least64_t`
and `int_fast64_t` types.  The underlying type is actually a `long long`.  Match
the types to allow the printf specifiers to work properly and have the compiler
vended macros match the implementation on the target.
