I just checked using our comparison programs. Please leave them there.
Without inline the performance drops with 10-20%, using gcc 3.4.4 / Cygwin.
For gcc 4.3.0 they do not have any measurable negative or positive effect.
However, they do not any harm, they are everywhere in Boost, removing
them cost time and is bad for old compilers, so let's keep them...
