  Actually, this is more of a problem with the libstdc++ test driver, which is
where all the compilation goes on. That's where you'd have to make the change. 
I imagine it's possible to to change this to compile the test cases only if
they don't exist, and the remove them optionally at runtime. This change would
in the libstdc++ test code. To do this for the GCC testsuite would require
changing the GCC test code in lib/gcc.exp. All DejaGnu does is supply the
infrastructure that enables the compilation to work regardless of whether this
is a native, or cross target. Whether a test case gets compiled is up to the
test driver of the application.
