In contrast, when you build in a separate build tree, +# you use a version of srcdir.mk that Configure created, which sets SRCDIR +# to the location of the source tree. + +# This is designed to be included by the top level make file, with +# SRCDIR being passed to all the submakes. That means that when you +# build in a separate build tree, you must build from the top; you +# can't go into a subdirectory and type "make".
