time_t is a typedef for long on Mac OS X. In 32-bit x86 (ILP32), long is
a signed 32-bit quantity, and its range does not contain the range of
uint32_t, used to store times in time_t fashion in minidump files. A
cast is necessary to make these EXPECT_* macros do the right thing. This
is not a problem in x86_64 (LP64) where long is a signed 64-bit
quantity, which does contain the range of uint32_t.
clang’s error was “error: comparison of integers of different signs:
'const long' and 'const unsigned int' [-Werror,-Wsign-compare]”
