It tries to link a simple program. Therefore it is better in some
sense, since it checks whether the function is implemented. Here is
some untested code (note that AC_CHECK_FUNC is an if-then-else thing,
while AC_CHECK_FUNCS defines HAVE_foo as needed):
lyx_use_xforms_image_loader=no
AC_CHECK_FUNC(flimage_dup,[
AC_CHECK_FUNC(flimage_to_pixmap,[
lyx_use_xforms_image_loader=yes
AC_CHECK_FUNCS(flimage_enable_ps)])])
AM_CONDITIONAL(USE_XFORMS_IMAGE_LOADER,
test $lyx_use_xforms_image_loader = yes)
Note that the x is not needed above because you know the variable is
not empty.
This defines the conditional USE_XFORMS_IMAGE_LOADER and the macro
HAVE_FLIMAGE_ENABLE_PS.
