// Added by Dave Laundon 19th August 2002
// 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.
