Browse source 
* configure.in (mcore-pe): Disable the configuration of
  libstdc++-v3 since exceptions are not supported.
* config/mcore/mcore.h (CC1_SPEC): Define only if not already
  defined.  Do not disable exceptions or rtti.
* config/mcore/mcore-pe.h (CC1_SPEC): Define before including
  mcore.h.  Disable exceptions and rtti, since they are not
  supported by EPOC.
