+Subject: [PATCH] opbible: improve Makefile, respect user's CXX, C(P|XX)FLAGS,
+ and LDFLAGS
+
+Make the Makefile respect the user's CXX, C(P|XX)FLAGS, and LDFLAGS by
+either using GNU Make's implicit rules or by appending instead of
+overriding the CXXFLAGS variable. This also has the nice advantage
+that the Makefile becomes more idiomatic and shorter.
+
+The Makefile not respecting user variables was initially report by
+Gentoo's CI and the following two downstream bugs:
