exceptions without libstdc++-v3?

[Adam Megacz]

I'm trying to hunt down the mystery problems with exceptions in
gcj-mingw by trying C++ exceptions first.

What do I need to link in to a program to get exception support?
libstdc++-v3 doesn't build on mingw -- do you need it in order to have
exception support?

$ cat test4.cc
class foo {
public: foo() {
}
};


int main() {
  try {
    throw new foo();
  } catch (foo* f) {
  }
}

$ /usr/local/gcc/bin/i686-pc-mingw32-gcc test4.cc -o test4.exe
