+Subject: [PATCH] build: Adapt to backwards incompatible change in GNU Make 4.3
+
+GNU Make 4.3 has a backwards incompatible change affecting the use of
+number signs or hashes (ie., #) inside function invocations. See:
+https://lists.gnu.org/archive/html/info-gnu/2020-01/msg00004.html
+
+In this case, it would expand the '\#' in the '\n\#include \"$(h)\"'
+argument to the foreach call to '\#', not '#'. This would lead to
+spurious backslashes in front of the '#include' directives in the
+generated fs-enumtypes.c file.
+
+Spotted by Ernestas Kulik.
