Hi Johannes,

I don't want to bother you with something which may certainly appear as
nitpicking compared to substance of your important work, but wanted to
remind only once that in in principle in GCC we have got some rather
strict coding conventions + some additional variants for the C++ runtime
library. That means, among other things, that in principle you should
always format to 80 columns and also that all the symbols should be
"uglifyied", that is should begin with single or double underscore. Just
browse a bit the other library sources...

Thanks,
Paolo.
