#  Transitionary check for the C++ ABI while we are switching provided

#  binaries from gcc-3.[23] to gcc-3.4 or later.  Currently gcc-3.[23]

#  is still the official compiler version to use, but experimental bi-

#  naries are released with a ".c2" suffix.

#  The CXX_ABI for gcc-3.[23] is 102, btw.

#  Note that the PACKAGE_RELEASE for the gcc-3.4 or later packages has

#  to be larger than that for the gcc-3.[23] packages (as long as both

#  are distributed) for smooth upgrade paths.
