+ * common prefix for all option macros of this kind is "SCM_DEBUG_". It is
+ * guaranteed that a macro named SCM_DEBUG_XXX is defined to be either 0 or 1,
+ * i. e. there is no need to test for the undefined case. This allows to use
+ * these definitions comfortably in macro code, as in the following example:
+ * #define FOO do { if (SCM_DEBUG_XXX) bar(); else baz(); } while (0)
+ * Any sane compiler will remove the unused branch without any performance
+ * penalty for the resulting code.
+ *
+ * Note: Some SCM_DEBUG_XXX options are not settable at configure time.
+ * To change the value of such options you will have to edit this header
+ * file or give suitable options to make, like:
+ * make all CFLAGS="-DSCM_DEBUG_XXX=1 ..."
