Aside from warnings, one reason for my patch was to allow this to compile

OK, I overlooked something. I first made the HTML patch using the htmHelp.h
and htmlHelp.lib
provided by the Html Help Workshop. But when I found out that you only have
to call a Hh.exe
I thought it would be better to make the compile inot dependent on this,
and provide my own
code to do it. I did want to keep the originl data type for HtmlHelp(),
though, becase in
future versions of Windows HtmlHelp might be so standard that it gets
defined in windows.h
like WinHelp() apparently is now, and then we could simply switch back to
it by deleting
my code for HtmlHelp.
The htmlhelp.h did contain the definition with DWORD_PTR, and since it did
not raise any
complaints from the compiler I assumed it was a standard Windows type, but
what I overooked
was that it was redefined it earlier in the file:
// Defines for Win64
#ifndef _WIN64
#define DWORD_PTR DWORD
#endif
HWND
WINAPI
HtmlHelpA(
HWND hwndCaller,
LPCSTR pszFile,
UINT uCommand,
DWORD_PTR dwData
);
HWND
WINAPI
HtmlHelpW(
HWND hwndCaller,
LPCWSTR pszFile,
UINT uCommand,
DWORD_PTR dwData
);
#ifdef UNICODE
#define HtmlHelp HtmlHelpW
#else
#define HtmlHelp HtmlHelpA
#endif // !UNICODE
