* configure.bat: Added support for --cflags and --ldflags

options that include quotes as long as command extensions are
enabled.  Specifically when -I, -L, and similar flags are used
to specify supplementary include and library directories a
directory name that includes spaces may now be used if it is
enclosed in quotes.

* INSTALL: Documented the change to configure.bat.

+  You may also use the --cflags and --ldflags options to pass
+  additional parameters to the compiler and linker, respectively; they
+  are frequently used to pass -I and -L flags to specify supplementary
+  include and library directories.  If a directory name includes
+  spaces, you will need to enclose it in quotes, as follows
+  -I"C:/Program Files/GnuTLS-2.10.1/include".  Note that only the
+  directory name is enclosed in quotes, not the entire argument.  Also
+  note that this functionality is only supported if command extensions
+  are available.  If command extensions are disabled and you attempt to
+  use this functionality you may see the following warning message
+  "Error in --cflags argument: ... Backslashes and quotes cannot be
+  used with --cflags.  Please use forward slashes for filenames and
+  paths (e.g. when passing directories to -I)."
+  
   N.B.  It is normal to see a few error messages output while configure
   is running, when gcc support is being tested.  These cannot be
   suppressed because of limitations in the Windows 9X command.com shell.
