We symlink our toolchain directory into the project, among other source component directories, and managed to hit the path length limitation when a standard header tried to include bits/c++config.h. As it seems, this bug must either be fixed via fixing up the path in MinGW to then forward it as extended path to Windows or it could be fixed by adding a manifest enabling long path awareness for the GCC binaries. I have seen that there already is a mechanism for enabling UTF-8 as default code page via manifest (gcc/config/i386/winnt-utf8.manifest). I do not think it would be much work to add the other option, but I am entirely unfamiliar with the build system and autotools.
