Gentoo Linux on ~amd64, software up2date

yes

yes, nothing changed. I just switch from gcc 3.4.3 profile to 4.0 profile and
the same way back.

using libtool, the whole library is automake/autoconf/libtool driven.

one library is the target, it finally consists of hundreds of c++ object
files, though, the target (.so) is indeed somehow rather big, but again, the
linking time wasn't an issue with gcc 3.x
the deps actually look like below:
trapni@battousai .libs $ ldd libswl-0.4.so.0.4.0
libpthread.so.0 => /lib/libpthread.so.0 (0x00002aaaab92b000)
librt.so.1 => /lib/librt.so.1 (0x00002aaaaba40000)
libdl.so.2 => /lib/libdl.so.2 (0x00002aaaabb49000)
libattr.so.1 => /lib/libattr.so.1 (0x00002aaaabc4d000)
libacl.so.1 => /lib/libacl.so.1 (0x00002aaaabd50000)
libgcrypt.so.11 => /usr/lib/libgcrypt.so.11 (0x00002aaaabe57000)
libgpg-error.so.0 => /usr/lib/libgpg-error.so.0 (0x00002aaaabfa7000)
libstdc++.so.6
=> //usr/lib/gcc/x86_64-pc-linux-gnu/4.0.0-beta20050402/libstdc++.so.6
(0x00002aaaac0aa000)
libm.so.6 => /lib/libm.so.6 (0x00002aaaac2b1000)
libc.so.6 => /lib/libc.so.6 (0x00002aaaac438000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaac671000)
/lib64/ld-linux-x86-64.so.2 (0x0000555555555000)
libnsl.so.1 => /lib/libnsl.so.1 (0x00002aaaac79c000)
