+Description: Fix FTBFS with GCC 7
+ GCC 7 warns us that the mangled symbol names of various functions are due to
+ change in C++17:
+   src/mongo/util/scopeguard.h:154:7: error: mangled name for 'mongo::ScopeGuardImpl1<void (*)(void*) throw (), char*>::ScopeGuardImpl1(const mongo::ScopeGuardImpl1<void (*)(void*) throw (), char*>&)' will change in C++17 because the exception specification is part of a function type [-Werror=c++1z-compat]
+ This appears to be mostly harmless in our case, since we're not building a
+ shared library. Also, MongoDB 3.2 does not boast C++17 compatibility.
+ Fix this by treating all C++17-compat errors as warnings.
+ Additionally turn format truncation errors back to warnings again for the time
+ being.
