# Starting with GCC 3.0, the brainiacs in the GCC team decided
# that all C++ programs should depend on libstdc++. Not only
# is this not necessary, but it *prevents* binary compatibility
# between different distributions of Linux (and even on other
# OS's that normally don't include the GCC version of libstdc++...)
#
# Also, GCC 3.0.x still has problems compiling some code. You may
# or may not have success with it. USE 3.0.x WITH EXTREME CAUTION!
#
# The following check uses "gcc" instead of "c++" or "g++"
# when compiling with older versions of GCC which don't have
# this ridiculous reliance on libstdc++.
