OK, here it is.

 Try to locate the X Window System include files and libraries.  If the
 user gave the command line options @address@hidden and
address@hidden@var{dir}}, use those directories.  If either or
-both were not given, get the missing values by running @code{xmkmf} on a

-for the files in several directories where they often reside.  If either

address@hidden to their locations, unless they are in directories
-the compiler searches by default.

 If both methods fail, or the user gave the command line option
 @option{--without-x}, set the shell variable @code{no_x} to @samp{yes};
