These include an unused variable left over from the command-line
refactoring; an explicit referencing of the module handle for
sspicli.dll which we really do deliberately load and then don't
(directly) use; a missing pointer-type cast in the Windows handle
socket code; and two 32/64 bit integer size mismatches in the types of
functions I was importing from system API DLLs.
The last of those are a bit worrying, and suggest to me that after
going to all that trouble to add type-checking of those runtime
imports in commit 49fb598b0, I might have only checked the resulting
compiler output in a 32-bit build and not a 64-bit one. Oops!
We're passing a pointer as 4th argument to WinHelp. Do not cast it to
DWORD which would truncate the pointer. Instead use UINT_PTR as that
is what WinHelp expects.
called load_system32_dll() which constructs a full pathname for the
DLL using GetSystemDirectory.
The only DLL load not covered by this change is the one for
gssapi32.dll, because that one's not in the system32 directory.

putting HTML Help into "single-threaded" mode. Furthermore, this requires
extra work from the application (message pumping via HH_PRETRANSLATEMESSAGE).
Thus, remove them and run Help in a secondary thread. This means that keyboard
input into the Index and Search tabs now works.

since even the latest version of w32api (3.6) shows no sign of HTMLHelp
support.
(This touches mkfiles.pl because that's where the details of what Cygwin
doesn't support are kept currently. This may be deliberate, so I haven't
changed it.)

and various calls to WinHelp() have been centralised into a new file
winhelp.c, which in turn has been modified to detect a .CHM file as
well as .HLP and select between them as appropriate. It explicitly
tries to load HHCTRL.OCX and use GetProcAddress, meaning that it
_should_ still work correctly on pre-HTML-Help platforms, falling
gracefully back to WinHelp, but although I tested this by
temporarily renaming my own HHCTRL.OCX I haven't yet been able to
test it on a real HTML-Help-free platform.
Also in this checkin: a new .but file and docs makefile changes to
make it convenient to build the sources for a .CHM. As yet, owing to
limitations of Halibut's CHM support, I'm not able to write a .CHM
directly, more's the pity.
