Weird, I don't have any dependency on the DLL for it:
$ ldd t.exe
ntdll.dll => /Windows/SYSTEM32/ntdll.dll (0x7ffc65560000)
ntdll.dll => /Windows/SysWOW64/ntdll.dll (0x770b0000)
wow64.dll => /Windows/System32/wow64.dll (0x5d1b0000)
wow64win.dll => /Windows/System32/wow64win.dll (0x5d210000)
Can you post the output of 'g++ foo.cpp -v' for your C++ testcase? Can you
find out what symbol(s) of libstdc++.dll are referenced by your executable?
