Not sure. It went down from 6 seconds to 2 seconds after running
autogen. But I do not know whether that is because your changes came
into effect, or because of caching.


I think it is my change. Caching is not enabled by default. You could 
try to enable it, but I am not sure that all our tests are well written 
in this repsect.



What is you typical workflow? Why do you run configure often by hand?


Distinct build directories, one configuration script per directory. I do
not run configure often, only when I want to make sure.


Normally it runs by itself.

This is when std::regex is available. With gcc 4.6 it takes less than a
second.




(but maybe the real problem is that autotools often want to run configure
even after I have just ran it by hand.)

Yes, I do not know how to make it faster. One issue is that we have to 
link. It might be that I should set optimization level later in configure.
