            Status: UNCONFIRMED
          Severity: normal

main config.log

Bootstrap fails under Win10 at configuring libgcc in stage2 with
x86_64-w64-mingw32 host/target. Bootstraps succeeds with 9-20181118 snapshot
with same configuration/toolchain and fails at the same point with later
snapshots.
Host: win10, mingw64 with gcc 8.1 + msys2
