WIN32 != cygwin
If you want cygwin-provided functions, build a cygwin version (i.e.
without -mno-cygwin). Otherwise, if the functions are not available
from MS libraries (which is what you are using when you build with
-mno-cygwin) you need to either (a) write replacements yourself, or (b)
complain to Bill G.
Further discussion of a non-cygwin build of GNUPLOT belongs elsewhere.
perhaps the mingw list?

You assume much: that the authors of Microsoft's runtime library,
msvcrt.dll, have ANY interest in cross-platform compatibility with

Right -- libm is a cygwin library, so it'll need cygwin1.dll. But, by
using -mno-cygwin, you're not USING cygwin1.dll for system services, you
are using msvcrt.dll.
