what is the right way to check for X extensions with autoconf 2.54?
Right now, we use
AC_PATH_XTRA
dnl Look for Xpm
AC_CACHE_CHECK(for Xpm library, gb_cv_have_xpm,
[ gb_LIBS_save=$LIBS
gb_CFLAGS_save=$CFLAGS
LIBS="$X_LIBS -lXpm $X_PRE_LIBS -lX11 $LIBS"
CFLAGS="$CFLAGS $X_CFLAGS"
AC_TRY_LINK([#include <X11/xpm.h>],
[XpmReadFileToPixmap(0,0,0,0,0,0);],
gb_cv_have_xpm=yes,
gb_cv_have_xpm=no)
LIBS=$gb_LIBS_save
CFLAGS=$gb_CFLAGS_save])
dnl Same thing with XShape
AC_CACHE_CHECK(for X shape extension, gb_cv_have_xshape,
[ gb_LIBS_save=$LIBS
gb_CFLAGS_save=$CFLAGS
LIBS="$X_LIBS -lXext $X_PRE_LIBS -lX11 $LIBS"
CFLAGS="$CFLAGS $X_CFLAGS"
AC_TRY_LINK([#include <X11/Xlib.h>
#include <X11/Xutil.h>
#include <X11/extensions/shape.h>],
[XShapeQueryExtension(0,0,0);],
gb_cv_have_xshape=yes,
gb_cv_have_xshape=no)
LIBS=$gb_LIBS_save
CFLAGS=$gb_CFLAGS_save])
Is there an equivalent standard idiom?
AC_SEARCH_LIBS comes to mind, of course, but it does not permit
additional #includes... Or maye they are not necessary at all?
Thanks!

There are 10 kinds of people: those who count in binary and those who do not.
