Saleem Abdulrasool: GCC complains about the template functions as potentially not being able to be

inlined.  These do not need to be always-inlined for ABI stability because they are not exported beyond this source due to the unnamed namespace.
Also simplified use of the Wmissing-field-initializers pragma as was done for clang.
