Ah! I thought I'd checked that already, but looking at the output now I can see what's going wrong. Cutting down to the relevant error: ssh: remote git-upload-pack '//home/Adam/vcs/Cygwin-Git/git-2.6.2-1.x86_64/build/t/trash directory.t5813-proto-disable-ssh/remote/repo.git' fatal: '//home/Adam/vcs/Cygwin-Git/git-2.6.2-1.x86_64/build/t/trash directory.t5813-proto-disable-ssh/remote/repo.git' does not appear to be a git repository Note the '//' at the start of the path -- on most *nix systems '//' is effectively identical to '/'. On Cygwin, however, '//' is used to access Windows UNC paths: what Windows calls "\\server\share", Cygwin calls "//server/share". If you replace the '//' with '/' you get the locatoin of the repository; but here Cygwin is looking for the repository in a share called "Adam" on a network server called "home"... I suspect the correct fix here is to fix whatever's causing Git to generate a path with that '//'. If nobody else gets to it soon (probably on the order of a week before I'll get the chance), I'll go code diving and submit a patch. > I tried building on Linux with the Cygwin build knobs found in > config.mak.uname, but I couldn't get it to fail.

If I recall correctly, the correct interpretation of '//' isn't defined in POSIX, so whatever's causing that path to be generated is the bit that's not fully portable. It looks as though t5813 throwing this up is just a coincidence rather than it being particularly related to the function those tests are actually testing.
