> Postfix stable release 3.4.1 is available.
upgrading, as per usual here, from a working 3.4.0 build to 3.4.1, now fails
cd postfix-3.4.1
make tidy
make -f Makefile.in MAKELEVEL= Makefiles
(echo "# Do not edit -- this file documents how Postfix was built for
your machine."; /bin/sh makedefs) >makedefs.tmp

make: *** [Makefile.in:31: Makefiles] Error 1
make: *** [Makefile:22: Makefiles] Error 2
this _is_ after recent update to Linux kernel 5.0.0.
looks like `makedefs` still refers only to
grep Linux.*\) makedefs
Linux.1*) SYSTYPE=LINUX1
Linux.2*) SYSTYPE=LINUX2
Linux.[34].*) SYSTYPE=LINUX$RELEASE_MAJOR
and may (?) need a Linux5 ...
