[Bug other/22499] New: 4.1.0-beta20050709: installation does not fully honour configure --*dir completely

["gcc at derived-software dot ltd dot uk" <gcc-bugzilla at gcc dot gnu dot org>]

Installing gcc-4.1.0-beta20050709 using a Gentoo ebuild resulted in an unusable
g++ - I think the problem is gcc installer related rather than Gentoo, though.

Gentoo builds gcc with the following configuration:
.../gcc-4.1-20050709/configure \
--enable-version-specific-runtime-libs \
--prefix=/usr \
--bindir=/usr/i686-pc-linux-gnu/gcc-bin/4.1.0-beta20050709 \
--includedir=/usr/lib/gcc/i686-pc-linux-gnu/4.1.0-beta20050709/include \
--datadir=/usr/share/gcc-data/i686-pc-linux-gnu/4.1.0-beta20050709 \
--mandir=/usr/share/gcc-data/i686-pc-linux-gnu/4.1.0-beta20050709/man \
--infodir=/usr/share/gcc-data/i686-pc-linux-gnu/4.1.0-beta20050709/info \
--with-gxx-include-dir=/usr/lib/gcc/i686-pc-linux-gnu/4.1.0-beta20050709/include/g++-v4
\
--host=i686-pc-linux-gnu --build=i686-pc-linux-gnu --disable-altivec
--enable-nls --without-included-gettext --with-system-zlib --disable-checking
--disable-werror --disable-libunwind-exceptions --disable-multilib
--disable-libgcj --enable-languages=c,c++,f95 --enable-shared
--enable-threads=posix --enable-__cxa_atexit --enable-clocale=gnu

The problem is that the installation process puts libstdc++ (and all the other
built libraries), as well as the fixincludes'd headers, into
/usr/lib/gcc/i686-pc-linux-gnu/4.1.0 rather than the locations specified by
bindir, datadir, and includedir.  Gentoo is (I believe correctly) assuming that
the runtime libraries should be in the directories it specified.

This appears to be caused by the following:

---[gcc/Makefile.in]---
...
libsubdir = $(libdir)/gcc/$(target_noncanonical)/$(version)
...
where libsubdir is then used for GCC_INCLUDE_DIR, and a lot of other things.
$(version) is set from the contents of the gcc/BASEVER file (containing "4.1.0").

There appears to be no way via configure to get the "expected" behaviour, which
is why I suspect it is a gcc issue...
