I second this. If for example I have

using clang : : : <cxxflags>"-Wno-logical-op-parentheses" ;

then whenever a project is built with <warnings>on or <warnings>all, 
-Wall is appended to the command line after the flags in user-config, 
making -Wno-logical-op-parentheses to lose its effect. If there was a 
way to specify that a certain flag should come near the end of the 
command line rather than near the beginning, that would solve my case.
