Even if it would triple or quadruple it, you'd still wouldn't notice a 
difference.

A few months ago I benchmarked the compilation of a fairly large (in the 100 
KLOCs range) C++ library, once with documentation (doxygen style) in the 
headers, and once without. On a 20mn compile (dual P-III 900, SCSI, 256MB), 
the difference was under 1 second.

Check it for yourself. Suppose all your config files total 2000 lines, say 80 
chars each, half of which begin with '#'. So that's 80,000 chars to scan. 
scanning an std::vector<char> of such a size takes 30ms on my machine (PIII 
600), 10ms if I compile with -O2.
