Author: arichardson Date: Wed Nov 29 21:16:14 2017 New Revision: 326375 URL: https://svnweb.freebsd.org/changeset/base/326375 Log: Don't fail the build due to clang integer constant range warnings This warning checks whether a constant is out of range of the integer type. An example is `comparison of 'u_int' > 4294967295 is always false` and in this case the warning makes sense. However, when the type is a typedef that can be either 64 or 32 bits the if condition is only tautological in some configurations so this should not be a warning that fails the build.
