yes.

investigating more, I noted that SunPro is detected correctly when we do
export CXX=CC
in the spec or build script, but fails when we do
export CXX="CC -library=no%Cstd -library=Crun -xannotate=no"

It looks like cmake somehow ends up calling
CC "-library=no%Cstd -library=Crun -xannotate=no"
the-rest-of-the-flags-here CMakeCXXCompilerId.cpp
which the Studio does not like:
$ CC "-library=no%Cstd -library=Crun -xannotate=no" CMakeCXXCompilerId.cpp
CC: illegal option usage -library=no%Cstd -library=Crun -xannotate=no
This is the same as observed in the cmake logs below.

Is this behaviour expected?
