[gnu.g++.lib.bug] find -f in Makefile isn't right in X style shadow dir

perm@MIZAR.DOCS.UU.SE (Per Mildner) (11/23/89)

libg++ 1.36.1

  We use the X11 utility lndir to create shadow dirs of the original
gnu sources.  This means that all directories are directories but
(most) files are symbolic links to the originals. This loses in
libg++/Makefile install-include-files target as that uses "find .
-type -f -print" to locate include files. We use "find . !( -type -d)
..." but that might not be the right way.
