@cindex MS-Windows file-name syntax
@cindex converting file names from/to MS-Windows syntax
On MS-DOS and MS-Windows, these functions (like the function that
actually operate on files) accept MS-DOS or MS-Windows file-name syntax,
where backslashes separate the components, as well as Unix syntax; but
they always return Unix syntax. This enables Lisp programs to specify
file names in Unix syntax and work properly on all systems without
change.
change.@footnote{In MS-Windows versions of Emacs compiled for the Cygwin
environment, you can use the functions
@code{cygwin-convert-file-name-to-windows} and
@code{cygwin-convert-file-name-from-windows} to convert between the
two file-name syntaxes.}

** Cygwin builds can use the native MS Windows user interface.
Pass --with-w32 to configure. The default remains the X11 interface.

** Two new functions are available in Cygwin builds:
`cygwin-convert-file-name-from-windows' and
`cygwin-convert-file-name-to-windows'. These functions allow Lisp
code to access the Cygwin file-name mapping machinery to convert
between Cygwin and Windows-native file and directory names.

Emacs now supports mouse highlight, help-echo (in the echo area), and
Emacs now supports `mouse-highlight', help-echo (in the echo area), and
