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