gperf (http://www.gnu.org/software/gperf/) is a utility app that
generates perfect hash functions. By perfect we mean that there are no
hash collisions in the lookup and thus some runtime performance
improvements can be had. Your cygwin/bin directory is supposed to have
a gperf.exe app in it. If not then you can run the cygwin install again
and add that package. It should be under the dev tools section of the
installer. I wonder if it would be better if code-generating utilities like gperf were run by code submitters once instead of being run by every WebKit user on every build. I think this results in WebKit builds being a bit slower than necessary. A no-change WebKit build takes a couple minutes for me, whereas other projects of comparable size take maybe 5 seconds to complete (though granted there are other things involved beyond auto-generated source files). I assume the WebKit tests make sure mistakes and omissions in code affected by this don't happen (or am I wrong about this?). Another benefit of this would be reduced build failures like that reported below. Please feel free to correct me if I am in error. Paul
