repost: libg++ won't build on alphaev56-dec-osf4.0d

[Alexandre Oliva]

Anyone got any idea on how to work around this problem?  I've had to
copy libg++.a to libg++.so after a failed build and continue from then
DU4.0 for more than a month :-(

It clearly means there's something wrong with the way shared libraries 
are being built on DU, but I don't have the faintest idea on how to
fix it :-(

I know I'm supposed to be able to overcome this problem, as the
maintainer of libtool, but I'm no DU hacker :-)

Any suggestions?

After installing Mark Mitchell's patch to work around the compilation
problem for libio in the latest snapshot and restarting the build in a
completely clean tree, I found the following problem:

make[2]: Leaving directory `/usr/local/tmp/egcs/alphaev56-dec-osf4.0d/libg++/src'
/usr/local/tmp/egcs/gcc/xgcc -B/usr/local/tmp/egcs/gcc/ -B/n/temp1/gcctest/egcs/alpha-OSF1-V4.0/alphaev56-dec-osf4.0d/bin/ -g -O2 -fno-implicit-templates  -shared -o libg++.so.2.8.1.2 `cat piclist` -L../libstdc++ -lstdc++ -lm
/usr/bin/ld:
/usr/local/tmp/egcs/gcc/libgcc.a(_eh.o): __throw: multiply defined
collect2: ld returned 1 exit status
make[1]: *** [libg++.so.2.8.1.2] Error 1
make[1]: Leaving directory `/usr/local/tmp/egcs/alphaev56-dec-osf4.0d/libg++'

None of the object files from libg++ define __throw, but __throw is
defined both in libstdc++.so and libgcc.a:

000003ffbffee700 T __throw

0000000000000a20 T __throw

Any clues?
