   3 # Until 2020-09-05, the .INCLUDEDFROMFILE magic variable did not behave
   4 # as described in the manual page.
   5 #
   6 # The manual page says that it is the "filename of the file this Makefile
   7 # was included from", while before 2020-09-05 it was the "filename in which
   8 # the latest .include happened". See parse.c, function ParseSetIncludeFile.
   9 #
  10 # Since 2020-09-05, the .INCLUDEDFROMDIR and .INCLUDEDFROMFILE variables
  11 # properly handle nested includes and even .for loops.
