This happens because you defined specific flags for the program or library.
See http://sourceware.org/automake/automake.html#renamed-objects
for an explanation.

You mean the script "compile", right?
(If you mean libtool, then I don't know, ask at the libtool list...)

I believe automake uses "if gcc" if configure detects it.  You should see
that Makefile.in contains both alternatives; configure then comments out
one of them.

I don't have a capacity to answer this, sorry; perhaps someone else...

Or you could try to look at some Gnome projects, how they link against
gtk++.  Try to ask on #gtk++ at irc.gnome.org for an example project.
(They sometimes have a "bad style" in autotools, but they have it working.
You get the best blend by applyiing the hints you have got from Ralf.)

Hope this helps,
