[AD] Building Allegro for MSVC using the latest Cygwin is broken

[Andrei Ellman <ae-a-alleg@xxxxxxxxxx>]

Hi,

The latest version of Cygwin comes with a 'coreutils' package that 
contains a program called 'link'. This clashes with MSVC's link.exe, so 
that whenever the 4.1.18 WIP build-process is linking something, it 
calls the wrong program.

For example...

obj/msvc/runner.exe link @ -nologo -release -subsystem:windows 
-out:tests/win/dibgrab.exe obj/msvc/alleg/dibgrab.obj lib/msvc/alleg.lib 
kernel32.lib user32.libgdi32.lib comdlg32.lib ole32.lib dinput.lib 
ddraw.lib dxguid.lib winmm.lib dsound.lib
link: too many arguments
Try `link --help' for more information.

typing link --help reveals that it's a gnu program.

And yes, I did remember to run vcvars32.bat in a dos-box and then start 
cygwin from within the same dos-box, so my MSVC environment variables 
have been setup.

Building the Mingw32 version of Allegro however works fine. Also, I have 
been able to build Allegro 4.1.18 WIP for MSVC using a two-year old 
installation of Cygwin.
