DOS and Windows, once you get past command.com, accept both 
slashes and backslashes. So filenames like 'c:/djgpp/gnu/autoconf-2.13' 
are just as valid as 'c:\djgpp\gnu\autoconf-2.13'. Which is why 
AC_PATH_PROG should now use the pattern '?:[/\\]' in the generated 
configure script to keep out DOS-specific relative paths.
