Here is my current extconf.rb:

--------
require 'mkmf'

if (/mswin32/ =~ PLATFORM)
    $CFLAGS+=" -GX "    # allow exceptions
end

$LIBS << " -lstdc++ -lc"

create_makefile("Test")
--------

Here is the result:

$ ruby extconf.rb
creating Makefile

$ make
cc  -bundle  -L"/usr/lib" -o Test.bundle Test.o  -lruby  -lpthread -ldl 
-lobjc   -lstdc++ -lc
/usr/bin/ld: Undefined symbols:
__Unwind_Resume
collect2: ld returned 1 exit status
make: *** [Test.bundle] Error 1

$ls
Makefile        Test.cpp        Test.o          extconf.rb
