Re: Linker Error with GSL/GNUWin32

["GnuWin32" <gnuwin32 at users dot sourceforge dot net>]

Most probably, you have mixed Cygwin and Mingw. If you want to create native
MS-Windows executables (i.e. executables that depend only on msvcrt.dll and
don not require installation of Cygwin), make sure that the Mingw bin
directory comes first in your path. If you want to create Cygwin
applications, then you cannot use the Gnuwin32 port of Gsl.
See the recent postings on this issue.

You might want to CC your message to the GNUWin32 list or the
maintainer of the GNUWin32 GSL package.  I'm not sure if they read
this list.  Looks like there is some sort of incompatibility between
the system libraries involved anyway.
