If I wanted to nitpick I'd say that since it's used only during the build it would be okay to have it in the description of the build environment but not in the one of the host environment, but if it has to descibe the build *process* rather than the build environment, then you are certainly right. > > Ah I quite like this idea, thanks!

Okay thanks for telling, the results looked a bit odd (e.g. name of default output file). > Okay.

Am I correct that you know all this merely by reading config.sub, or is there another documentation I am not aware of? > If you are happy to > interpret "--host=windows", (or any canonical triplet which ends with > "-windows"), to implicitly require cl.exe, then you could adapt: > > AS_CASE([$host_alias],[*windows | *mingw*cl],[CC=cl.exe]) > > or otherwise, you could qualify it: > > AS_CASE([$host_alias],[*windowsmsvc | *mingw*cl],[CC=cl.exe]) Yeah, I think I am happy with this solution. At least as a starting point. Why would you keep the two cases by the way? Wouldn't one be enough? I mean, am I correct that the mingw*cl could be removed? > > For the 64 bits architecture, it seems the followingworks: > > > > ./configure --build=x86_64-unknown-cygwin --host=x86_64-pc-windows > > CC=cl > > This should also work, with any of the preceding adaptations. > > > Do you guys think I can proceed with these values for build and > > host? > > I don't see why not; you've nothing to lose by trying. Indeed. Many thanks for having helped with this!
