would need to try that out on Windows, but my guess is that even if it

half of them but that is bad enough) for every included files, and those
file accesses take forever on Windows.


^^ This!

IIRC, Mathias Bauer benchmarked that once and noted that on Windows each added
path has a significant impact on buildtime, so you really dont what to go
laissez-faire with those. Also the order of -I-switches can be quite important.
