Unless your name is BartC, you must not say things such as: that a C library
function for string manipulation is or is not supported by Windows.

:)

You note that strsep is in Newlib. And that means it is in Cygwin.
So, that is on Windows.

  $ ./txr

  Quit with :quit or Ctrl-D on an empty line. Ctrl-X ? for cheatsheet.

The Cygwin DLL makes a decent run-time library for Windows executables,
with lots of POSIX support as well as BSD functions like this, yet with access
to Windows API's too.

With the Cygnal fork of the cygwin1.dll, you can deploy Cygwin-compiled
executables such that they exhibit more native behaviors. (See signature).
