It is a Cygwin, but it is not a bug, rather - intended behavior. You can get around it by setting "noacl" flag on mount points you want to be managed by Windows, or explicitly chmod +x necessary binaries. (Though, they SHOULD be chmod'd in the git. Else it is just not suitable for the job of VCS.) > It is more likely that the problem was caused by either a security policy or > the "IT approved" version of cygwin had been modified.
