Hi all, I've dug into the gdb sources. The problem is in the cygwin-only part and is not about the PATH variable but about one single DLL file name. This path length is *fixed* to 512 characters (SO_NAME_MAX_PATH_SIZE) for the *realpath* of the DLL. So there's no way for the user to work around this apart from shortening the directory or file names.
