This looks *much* better now:
  http://buildfarm.opencsw.org/~dam/automake-1.12.5-2012-11-26/
However, what I don't understand is that I especially select Sun Studio compiler which
accepts the defined LDFLAGS. Why does automake try to test gcc stuff with the flags?
I mean, if I set the compiler to gcc and pass gcc flags it would probably also work.


Best regards
