## @deftypefn {} {@var{mingwpath} =} __w2mpth__ (@var{winpath})
## Convert a Windows-style relative or full path name to MinGW style.
##
## @strong{Caution:} __w2mpth__ does not check the validity of the path.
##
## Examples:
##
## @example
## @group
##   mpth = __w2mpth__ ('D:\full\path\to\file.dat')
##   @result{} '/D/full/path/to/file.dat'
## @end group
## @end example
##
## @example
## @group
##   mpth = __w2mpth__ ('relative\path\to\file.dat')
##   @result{} 'relative/path/to/file.dat'
## @end group
## @end example
##
## @end deftypefn

function mingwpath = __w2mpth__ (winpath)

  ## Check for platform
  if (! ispc)
    error ("__w2mpth__: function must only be called on Windows platforms\n");
  endif

  ## Replace backslash file separators by forward slashes
  mingwpath = strrep (winpath, '\', '/');
  ## Also treat drive letter but beware of relative filenames
  mingwpath = regexprep (mingwpath, '^([a-zA-Z]):', '/$1');

endfunction


## Use single quote strings for winpaths to cope with backslashes.
## These tests are commented out until a better place is found (bug #44581)
