comment. * mount.cc (mount_info::from_fstab): Use tmp_pathbuf rather than stack for big local buffer. * net.cc (cygwin_gethostname): Call GetComputerNameExA rather than GetComputerNameA if gethostname failed. * shared.cc (user_info::initialize): Fix formatting. * include/sys/file.h: Define flock and accompanying macros if not already defined in sys/_default_fcntl.h.
