+# ccswitch.strs: project-agnostic list of compiler switches,
+# for which support is tested by default.
+
+# when -foo is supported by the host or native compiler, add
+# ``CFLAGS_foo = -foo'' to the respective ccenv variable file
+# (that is, ccenv/host.mk or ccenv/native.mk).
+
+# the make variable prefix is _CFLAGS_ or _NATIVE_CFLAGS_,
+# to which the compiler-switch, minus leading dashes and
+# trailing equal-sign or comma, is appended; non-leading
+# dashes and non-trailing equal-signs and commas are then
+# substituted with underscores.
+
+# the project-agnostic list below can be supplemented by a
+# project-specific one, named project/config/ccswitch.strs.
