+# Test for the .include directive combined with fatal errors.
+#
+# At 2020-09-13, the code in Parse_File that sets "fatals = 0" looked
+# suspicious, as if it were possible to suppress fatal errors by including
+# another file.  It was a false alarm though, since Parse_File only handles
+# the top-level makefiles from the command line.  Any included files are
+# handled by Parse_include_file instead, and that function does not reset
+# the "fatals" counter.
+
+# Using an undefined variable in a condition generates a fatal error.
+.if ${UNDEF}
+.endif
+
+# Including another file does not reset the global variable "fatals".
+# The exit status will be 1.
+.include "/dev/null"
+
+# Adding another file to be included has no effect either.
+# When the command line is parsed, the additional file is only enqueued
+# in the global "makefiles" variable, but not immediately run through
+# Parse_File.
+.MAKEFLAGS: -f "/dev/null"
