Уважаемые коллеги!
борясь с --as-needed в одном кривом софте (yacas), 
заметил, что его библиотеки имеют undefined symbols из libstdc++,
и действительно, линкуются gcc:

gcc -shared  .libs/deffile.o ...
./.libs/libyacasnumbers.so ./.libs/libyacasplatform.so -lm -ldl
-march=athlon -Wl,--as-needed -Wl,-soname -Wl,libyacas.so.0 -o
.libs/libyacas.so.0.0.0

однако это получается из

../libtool --mode=link g++ -pipe -Wall -O2 -march=athlon -Wall 
-Wl,--as-needed -o libyacas.la -rpath /usr/lib deffile.lo ...
... <other>.lo libyacasnumbers.la libyacasplatform.la -lm -ldl

где явно указан g++.

Кто знает в чем причина?
