#
# 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.
.if !defined(.INCLUDEDFROMFILE)
# expect+1: main-before-ok
. info main-before-ok
.else
. warning main-before-fail(${.INCLUDEDFROMFILE})
.endif
.for i in once
. if !defined(.INCLUDEDFROMFILE)
# expect+1: main-before-for-ok
. info main-before-for-ok
. else
. warning main-before-for-fail(${.INCLUDEDFROMFILE})
. endif
.endfor
.include "include-sub.inc"
.if !defined(.INCLUDEDFROMFILE)
# expect+1: main-after-ok
. info main-after-ok
.else
. warning main-after-fail(${.INCLUDEDFROMFILE})
