Put the C compiler flags determined by @code{AC_FIND_X} into @code{make}
variable @code{X_CFLAGS}, and the linker flags it determined into
@code{X_LIBS}. If X is not available, put @samp{-DX_DISPLAY_MISSING}

An enhanced version of @code{AC_FIND_X}. Put the C compiler flags that
X needs into @code{make} variable @code{X_CFLAGS}, and the X linker
flags into @code{X_LIBS}. If X is not available, put
@samp{-DX_DISPLAY_MISSING} into @code{X_CFLAGS}.
Also check for special libraries that some systems need in order to
compile X programs. Add any that the system needs to @code{make}
variable @code{X_EXTRA_LIBS}. This macro calls @code{AC_FIND_X} and

you should let it call @code{AC_FIND_X} rather than doing that yourself.
