Bugzilla Bug 164555

emul-linux-x86-compat-1.0-r3 introduced a bug where it does not include
libstdc++.so.5 or libstdc++.so.6  ... v1.0-r2 included those files. 
32bit-binary applications like mozilla-firefox-bin will not run without
libstdc++.so.5


Reproducible: Always

actually, compat should _only_ provide libstdc++.so.5  and not libstdc++.so.6,
since gcc provides the 32bit .so.6:
/lib64/gcc/x86_64-pc-linux-gnu/4.1.1/32/libstdc++.so.6
/lib64/gcc/x86_64-pc-linux-gnu/3.4.6/32/libstdc++.so.6

GCC 3.3 is not installed on most(any?) amd64 systems, so no libstdc++.so.5
exists.

If you do not have a gcc3, sync and re-emerge emul-linux-x86-compat-1.0-r3

It was first released without a test for gcc 3.x availability on your system,
which caused libstdc++.so.5 never to be installed.

emerge --sync && re-emerge

I assume it was _just_ committed and hasn't hit the rsync mirrors yet ...

Shouldn't:

        if has_version =sys-devel/gcc-3.4*; then

be:

        if has_version =sys-devel/gcc-3.3*; then

in the ebuild?
GCC 3.4 doesn't provide libstdc++.so.5, but GCC 3.3 does, I have gcc-3.4.6-r2
installed, and it sure isn't there:
