1) It should not check (and fail), if no C++ is needed (e.g. -no-dshow 
or on non-intel machines), 

2) It should not be needed to use $CC as C++ compiler, too.

3) The error 

# Please downgrade(upgrade) gcc compiler to gcc-2.95.2+ or gcc-3.0+ version

if compiling fails is misleading, because this time, it might really _not_ be 
gcc's fault (but mine: setenv CC=foobar ;-)
