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.

In GNU Emacs 26.0.90 (build 2, x86_64-w64-mingw32)

of 2017-10-17 built on MONOLITH

Windowing system distributor 'Microsoft Corp.', version 10.0.15063
