+# mean things like
+# 
+# 	configure CC=XXXX   # XXXX in { gcc, clang, tcc } or native platform cc
+# 	configure --prefix=/path/to/install
+# 
+# And the few other current configure options like --with-whiny-user-strftime,
+# --disable-nls, etc.  I don't know if we need all the standard configure options,
