Not sure what "the next step" is. . .

Note that the source of the LPCWSTR vs LPWSTR (which is the first
problem I hit:

  C:\C64\usr\local\src\xemacs-21.5-64bit\src\intl-auto-encap-win32.c(634)
  : error C2664: 'OpenDesktopW' : cannot convert parameter 1 from
  'const unsigned short *' to 'unsigned short *' Conversion loses
  qualifiers

is caused by this discontinuity:

VC98/include/winuser.h:

   OpenDesktopW(
       LPWSTR lpszDesktop,
       DWORD dwFlags,
       BOOL fInherit,
       ACCESS_MASK dwDesiredAccess);

/usr/include/w32api/winuser.h:

     WINUSERAPI HDESK WINAPI OpenDesktopW(LPCWSTR lpszDesktop,
                                          DWORD dwFlags,
                                          WINBOOL fInherit,
                                          ACCESS_MASK dwDesiredAccess);

I'm guessing this is simply because w32api has been updated to a later
version of Visual Studio include files. . .
Hmm, maybe not -- online MS documentation has LPWSTR, as above. . .

Some apparently mingw versions of winuser.h I can find on the web
have the non-const version. . ., but I can't immediately find any
discussion of the issue.

Since the only function with the LP[C]WSTR issue which is actually
_called_ by XEmacs is GetNamedSecurityInfo, for the time being I tried
editting intl-encap-win32.c to skip all the others, editting
w32api/aclapi.h to change LPCWSTR to LPWSTR and then rebuilding
intl-auto...

Ah -- I guess I see what you were worrying about.  GetWindowLongPtr
and friends are not supported by VS6.  Full stop.  What level is the
VS6 requirement/where is it coming from?  VS2008 an option?
