But thanks for trying. I've had a change of heart; or rather, while comparing David's build specification with my own, I had one of those "light-bulb" moments. (Specifically, GCC's configure scripts don't respect the convention, as normal autoconf generated scripts *should*, that $target may be inferred by propagation from $host, unless explicitly specified otherwise). When I explicitly specify "--target=mingw32", in addition to the already required "--host=mingw32", then I can achieve a successful build; however, the step at which the build previously choked -- a self-test feature which is new in gcc-7.x -- still seems to be of questionable value, for it tests the capabilities of the build compiler, rather than the one we're actually building, (contrary to the intent indicated by comments in the Makefile)! >> You might want to try building it yourself; My Windows native build >> has very few problems. > > I might do that if I find enough free time.

FWIW, a native bootstrap on my GNU/Linux box takes around 5 hours, (and is necessary if I want an Ada enabled tool chain, because gcc-ada-6.3.0 cannot build a gcc-ada-7.3.0 cross); I've never built GCC natively on Windows, but my experience with other packages suggests that it could take an order of magnitude longer. Once I have the native build, using that to build a Linux-hosted mingw32 cross compiler takes around 2 hours more, then a further 1½ to 2 hours to complete a cross-native mingw32 deployable build. If you're interested, I've attached my build specification, which I run through mingw-pkg thus: $ mingw-pkg --option="configure --target=mingw32" configure to configure the cross-native build, using that option in addition to the "--build" and "--host" options, (which my mingw-pkg local configuration supplies), and the aggregation of the package specific "option configure" settings from the build specification file. I believe my choice of options should be fairly self-explanatory, but if you'd like clarification of any, please ask. Additionally, if you'd like to see the patch-set I've used, you will find it in the "arch/mingw32" directory of the source tarball on OSDN. -- Regards, Keith.
