The value of LONG_MAX is dependent on the host environment used to build the compiler. For example X86-64 Windows has a different value than X86-64 Linux. Using LONG_MAX would give inconsistent results when cross compiling.

I wonder if the test added in #<!-- -->65559 is generating a warning on X86-64 Windows, but the CHECK-NOT doesn't fail because the warning would say 2147483647 instead of 4294967295.
