installing libraries/headers

["Andreas.P.Priesnitz" <priesnit at math dot uni-goettingen dot de>]

Hello!

Having finally managed to install gcc-3.0 for different alpha*-dec-osf4.0f,
I wonder about the fact that I could not influence where to install 
libraries/headers. For whatever configure options, they always end up in:
$(libdir)/gcc-lib/$(target)/3.0/(include/)

I would like, though, to have links in $(libdir) pointing to the runtime
libraries (installed in some subdirectory), so they are found via the standard
LD_LIBRARY_PATH.
Now, I create these links myself, but I wonder if it is an error that they are
not generated by the installation itself as in previous releases.
The alternative solution of installing the libraries directly in $(libdir)
with `--disable-version-specific-runtime-libs' worked neither (this solution
would be fine for me, as I use GNU stow, so I have different installation
directories for different versions/architectures anyway).

And I'd like the architecture-independent headers to go to a directory
common to all architectures, but
 --with-gxx-include-dir=...
did not have the desired effect.

Before trying to develop a fix (or a more thorough description) for this
problem, I would like to ask if I missed something or if this will already be
different in gcc-3.0.1 ?
I searched for quite a while in the mailing lists, but the only recent and
related comment I found was bug report #4039.

Does someone have more insight and the will to broaden my knowledge?
I would be happy and thankful about that!
Andreas
