Thanks a lot for your kind reply!

are you watching CLISP development? :-)

yes, this does the trick!
thanks!

interesting.
the above version is shorter and easier for me (and, more importantly,
those who will come after me) to understand, so I will stick with it.

AC_LANG_PROGRAM?

| cl_program_xcheck=`cat <<\EOF
| AC_LANG_PROGRAM([#include <sys/socket.h>
| #include <X11/Xlib.h>
| #include <X11/Xauth.h>],
| [XauGetAuthByAddr(AF_INET,0,"",13,"localhost:0.0",13,"localhost:0.0");])
| EOF`
this expands to
~ cl_clx_XauGetAuthByAddr_program=`cat <<\EOF
/* confdefs.h. */
_ACEOF
cat confdefs.h >>conftest.$ac_ext
cat >>conftest.$ac_ext <<_ACEOF
/* end confdefs.h. */
#include <sys/socket.h>
#include <X11/Xlib.h>
#include <X11/Xauth.h>
int
main ()
{
XauGetAuthByAddr(AF_INET,0,"",13,"localhost:0.0",13,"localhost:0.0");
~ ;
~ return 0;
}
EOF`
which does not look right.
