bug#28888: 26.0.90; nt/INSTALL.W64

I noticed the following errors in the 64-bit Windows build instructions
in the file nt/INSTALL.W64 when using a new MSYS2 installation.

The library liblcms2 is not currently available using pacman, which
causes the pacman command shown to fail, but it works if that library is
removed. It might be best to recommend trying to install liblcms2
separately, in the hope that it will become available in the future.

There is no file mingw64_shell.bat in the \msys64 folder. However, there
is an item labelled "MSYS2 MinGW 64-bit" in the Windows Start menu,
which seems to work correctly. Also, msys2_shell.bat is actually
msys2_shell.cmd.

Apart from the above issues the build went well and the resulting
version of Emacs seems to have worked correctly so far.

There is some ongoing discussion on this in Bug#28601.

Actually, the package was just renamed to mingw-w64-x86_64-lcms2.

Can you check what that item links to?  I guess it should be
C:\msys64\mingw64.exe (which is also one of the updates discussed in
Bug#28601).

Did you change the Windows PATH?  The instructions currently suggest
this, but it seems no longer needed for Emacs 26, and it causes some
extra complication with Msys find vs builtin Windows find.exe.

OK, I'll try that when I build the next update. Thanks.

"MSYS2 MinGW 64-bit" in my Windows Start menu is a shortcut to "C:\msys64\m=
sys2_shell.cmd -mingw64".

No, I didn't change the Windows path because I don't want this new MSYS env=
ironment to get mixed up with my normal environment. The build ran fine wit=
hout any modification to my path. The various options to start a MSYS shell=
 seem to set the path appropriately within that shell and Emacs runs fine f=
rom the shell. However, it doesn't find various required dlls when I run it=
 outside a MSYS shell and it requires more dlls than I had expected. The mo=
st obvious is libXpm-noX4.dll, but libgnutls-30.dll requires another 10 dep=
endent dlls! So a full set of dlls is going to be quite big.

Best wishes, Francis
