+# -O2           -> Perform second-level optimisations.
+#                  Not -Os because most/all x86 aren't starved for space.
+# -ggdb         -> Generate GDB debugging information.
+#                  This is used with splitdebug to make -dbg split packages.
+# -march=pen... -> Require a Pentium III or newer.
+# -mtune=pen... -> Tune for Pentium M processors.
+#                  More Pentium M netbooks exist than many realise, and they
+#                  are more likely users of Adélie than Pentium III.  This
+#                  makes code more performant on the larger base of machines.
+# -mfpmath=sse  -> Use SSE for all floating point math.
+#                  Since SSE is always available, this knob ensures that GCC
+#                  will take advantage of it over preferring 387 math.
