+Subject: [PATCH 2/2] makefile: replace remaining "-O3" with $(CFLAGS).
+
+Some time in the past, $CFLAGS was inserted into most of the build
+rules, and defaulted to "-O3 -Wall" if the user does not override
+that. However a few lingering "-O3" and "-O3 -Wall" remain hard-
+coded in the makefile. Here we fix that.

+Subject: [PATCH 1/2] makefile: add $(LDFLAGS) to commands that induce linkage.
+
+Like the more-familiar CFLAGS, there is a standard variable called
+LDFLAGS that should be used while linking libraries and executables.
+The default compilation rules for POSIX make include it,
+
+  https://pubs.opengroup.org/onlinepubs/9699919799/utilities/make.html
+
+This commit adds LDFLAGS to the custom makefile commands that link
+either an executable or a shared library.
