+// For all internal functions, use of stdcall calling convention moves the
+// responsibility for tidying the stack to callee from caller, reducing the code
+// involved considerably.  Gives an instant saving of 0.5K.
+// NB - the zlib and bzip2 portions have been given the same treatment, but with
+// project compiler-options settings and/or project-wide defines.
+// NB - safer for NSIS's routines to be defined explicitly to avoid problems
+// calling DLL functions.
