+# has been removed. According to the official description of DESTDIR by Gnu at

+# prepended to the normal and complete install path that it precedes for the 
+# purpose of installing in a temporary directory which is useful for building 
+# rpms and other packages.  The '/' after ${DESTDIR} will be followed by another 
+# '/' at the beginning of the normal install path.  When DESTDIR is empty the  
+# path then begins with '//', which is incorrect and causes problems at least for 
+# Cygwin.
