#4669: Lots of warnings from is_unsigned.hpp
 Reporter: Per Ola Ingvarsson <pi@…> | Owner: johnmaddock

Milestone: To Be Determined | Component: type_traits
  Version: Boost 1.43.0 | Severity: Problem
 Keywords: |
 When compiling programs that in some way use is_unsigned_imp, warnings
 from boost obscure the warnings that I'm interested in (i.e. the ones that
 I have caused myself). The same problem exists with is_signed_imp.
