Then how would I use default values set for stdlib in sun.jam namely,
sun-stlport, apache and gnu?
42 feature.extend stdlib : gnu ;
43 feature.compose <stdlib>gnu
44 : <cxxflags>-std=c++03 <linkflags>-std=c++03
"--bjam-options=-j8 toolset=sun stdlib=gnu cxxflags=\"-std=c++11\"
just overwrites default value for cxxflags and linkfags as specified in

Correct, as you notice, it works fine if for regression tests I update
my user-config.jam and not touch sun.jam.
However, I wanted to update sun.jam as users will not be aware of adding
this option(-library=stdcpp,CrunG3) to linkflags when they test the
released boost 1.60 version and wanted to test it out before submitting
a PR by using default sun.jam values.

No, its a recent message.
