"Could it be that when compiling and installing gcc with --enable-languages=c++ only gcc doesn't install some essential libs?"
Why in the world are you creating your own gcc? I used to do it just because I wanted to use the gcc-3.1 code, but it is darn tricky and completely unneccessary now, as gcc comes pre-built in the devel directory. If there is something unique you want to do with a version of gcc, make a parallel build, don't build over Cygwin's gcc. When I was creating my own stuff, I was creating it as an additional compiler to the Cygwin compiler. I created it in a directory I called mygcc. And I believe, if memory served, when I compiled I had to do something like the following (I had aliased my new compiler to newg++): newg++ hello.cpp -L\mygcc\lib to make sure that the libstdc++ stuff got found. But again, I would not do a build of gcc now, certainly not one that replaces the Cygwin binaries.
