[patch][win32] Improve building with VC2015

[Ken Takata]

Hi,

I wrote a patch for improving VC2015 support.

* Add src/msvc2015.bat.
* Update makefiles so that subsystem version can be properly specified.
(gvimext.dll, install.exe, uninstal.exe, tee.exe and xxd.exe)
* Update src/INSTALLpc.txt.
(Also includes updated description of MZSCHEME_VER.)

According to *new-msvc-windows-xp* in INSTALLpc.txt, we need some settings
for targeting Windows XP using VC2012 or later. However, the settings were
not so easy. msvc2015.bat makes it easier.

Thanks, I'll check it out next week.

Building works for console and gvim, now I'm trying to build with
interfaces.

The instructions for Ruby say:
cd ruby
win32\configure.bat

For me this always fails with:
win32\rtname: conftest.exe is not linked to msvcrt

Even though it just build. Any way to fix this or work around it?
I installed Ruby 2.2.6 and now using msvc 2015.

Unfortunately, Ruby 2.3 or earlier cannot be built by VC2015 or later.
Only Ruby 2.4 (or later) can be built by VC2015 or later.

Aha, that's why I didn't manage to figure it out. I'll change the
instructions to use Ruby 2.4 by default, since it will now also
recomment MSVC 2015.

Next problem is that TCL doesn't work:
libcmt.lib(initializers.obj) : warning LNK4098: defaultlib 'msvcrt.lib' conflict
s with use of other libs; use /NODEFAULTLIB:library
msvcrt.lib(_chandler4gs_.obj) : error LNK2001: unresolved external symbol __exce
pt_handler4_common

Hi Bram,

ActiveTcl should be also updated to 8.6.6. That's the reason why I had to
update the compiler to VC2015 on the vim-win32-installer repository.

You might also need an additional build option: TCL_DLL=tcl86t.dll
(Actually, I don't set this on vim-win32-installer yet. When I tried to set
it, if_tcl couldn't find the DLL on AppVeyor but it worked on my local PC.
Not sure what's happen.)

Hi Bram,

I thought I had sent the following patch about TCL_DLL:

--- a/src/INSTALLpc.txt
+++ b/src/INSTALLpc.txt
@@ -721,6 +721,10 @@ When building, you need to set the follo
TCL_VER: Tcl version in a short format. E.g. 86 for Tcl 8.6.X.
TCL_VER_LONG: Tcl version in a long format. E.g. 8.6 for Tcl 8.6.X.

+Sometimes the Tcl dll name changes. E.g. ActiveTcl 8.6.4 comes with tcl86.dll
+but ActiveTcl 8.6.6 comes with tcl86t.dll. You can set the dll name by settin

+
E.g. When using MSVC (as one line):

nmake -f Make_mvc.mak

But this was not included in v8.0.0989.
Isn't this or something similar description needed?

It's there in my local version. I'll make some more changes for MSVC
2015 to help users pick the right version of everything.

Thanks, I deleted all existing tcl versions and installed 8.6.6 (32 bit
version) and that worked.

I do need to add that, otherwise Vim looks for tcl86.dll, while the
distribution has tcl86t.dll. Not sure what the "t" stands for.

Now I'll give Lua a try...
