++;;; WINDOWS-1251
++;; On Windows platforms `windows-1251' coding system is defined in
++;; mule-win32-init.el using support for codepages provided by Microsoft
++;; libraries.  But on Unixes we have no built-in support for windows-1251, so
++;; we have define it here using ccl.
++
++;; '#-FEXP' is a special syntax for lisp reader.  Means 'ignore the next sexp
++;; when the FEXP is true'.  Here reader ignores code for windows-1251 when
++;; (featurep '(or windows-nt cygwin32)) is true.
