Automake warnings

[Mojca M. <moj...@gm...>]

Hi,

I wanted to test the latest gnuplot, but automake (1.14) keeps complaining:

 ./prepare

automake: At least a source file is in a subdirectory, but the 'subdir-objects'

subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.

It nevertheless works, but it would be great to fix these problems (I
know that I can probably downgrade autotools, but ...).
