A am affraid you did not notice what I wrote several times:
there is no pricipal reason for graphic/hyperdoc to be
compiled in the same way as FRICASsys. I know that some
Windows folks strongly dislike Cygwin. But Cygwin is
reasonable way to get graphical parts to Windows. Given
that sbcl seem to be incompatible with msys2.dll, we
should build FRICASsys without linking to it or Cygwin
DLL. But this does not exclude using Cygwin program
as helpers (in similar spirit to using msys2 tools for build).
Actually, cmucl port have similar spirit: cmucl is still 32-bit,
but C executables are build as 64-bit code.
Of course, real Windows lover would replace X11 calls by calls
to Windows API.
