Ok, I found out that the bug is not (entirely) in make. What causes this
problem is the following patch applied by MSYS2 packages of mingw make:
diff -Naur make-4.2.1/main.c make-4.2.1.new/main.c
--- make-4.2.1/main.c 2016-05-31 09:17:26.000000000 +0200
+++ make-4.2.1.new/main.c 2017-02-20 22:55:09.051617838 +0100
@@ -1126,8 +1126,11 @@
#endif
+/* setlocale interferes with line buffering if using parallel make on
MinGW */
+#ifndef __MINGW32__
/* Set up gettext/internationalization support. */
setlocale (LC_ALL, "");
+#endif
/* The cast to void shuts up compiler warnings on systems that
disable NLS. */
(void)bindtextdomain (PACKAGE, LOCALEDIR);
If I revert the patch, delete works as expected.
I'll file a bug there.
