Hello, on Cygwin 3.6.6-1.x86_64 on CYGWIN_NT-10.0-19045/Win10 I get
these errors from git fsck when working on a clean clone of the
gcc.git repro:
git fsck

git fsck then exits with error code 8, breaking our scripts.
Is this a Cygwin bug or feature running wild?
Yes.
These .cygXXX files are made by the cygwin DLL (I think it's something
like a hardlink to the running executable so we can fork even if it's
deleted, but I might well be misremembering the details) and are
supposed to get automatically removed.
Obviously, 'git fsck' objects to their presence, but it is safe to
remove them.
