Building typelib + dyncall with clang

Hi,

I tried to build typelib with clang, but the dyncall-0.6 ruby bindings
contain gcc specific assembly code.

In dyncall-0.7, this has been fixed. I did a quick test, and both
typelib + dyncall 0.7 can be compiled with clang/clang++. However, the
typelib test suite fails:

$ ./typelib_testsuite
Running 42 test cases...

*** 5 failures detected in test suite "typelib"

While the toolchain built with gcc + dyncall-0.7 only fails with:

$ ./typelib_testsuite
Running 42 test cases...
/home/kaltan/vbox/hudson/jobs/bootstrap-toolchain/workspace/CORBA_IMPL/TAO/Compiler/gcc/TARGET/gnulinux/arch/amd64/branch/toolchain-2.5/orocos-toolchain/typelib/test/test_marshalling.cc(93):
fatal error in "test_marshalling_simple": critical check -1 ==
memcmp(&a, &reloaded, sizeof(A)) failed [-1 != -256]

*** 1 failure detected in test suite "typelib"

So this seems more related to clang than to upgrading to dyncall-0.7.
Also note that I had to set 'CC=clang' as environment variable, since
the dyncall build detects its own compiler and does not pickup the one
from cmake/typelib.

BTW, there's also a pretty serious warning here:

[ 19%] Building CXX object typelib/CMakeFiles/typeLib.dir/pluginmanager.o
/home/kaltan/vbox/hudson/jobs/bootstrap-toolchain/workspace/CORBA_IMPL/TAO/Compiler/clang/TARGET/gnulinux/arch/amd64/branch/toolchain-2.5/orocos-toolchain/typelib/typelib/pluginmanager.cc:66:9:

      but has non-virtual destructor [-Wdelete-non-virtual-dtor]

which should be fixed by making the destructor virtual in
Typelib::TypeDefinitionPlugin
