 Ah.  Figured it out.  I missed this part of your original bug report:
 
     configured with: ../src/configure [...] --prefix=/usr
 
 Don't configure with --prefix=/usr unless you're a system vendor setting
 up a distribution.  It severely confuses GCC's idea of which headers
 are system headers and which headers are yours.  In this case, the C++
 library headers (normally "system") are being detected as yours.
