The appended patch against the branch works fine, but I noticed a new problem, since in gcc we have that for libgcc_s.so.1 in gcc/config/libgcc-glibc.ver: %inherit GCC_3.0 GLIBC_2.0 GLIBC_2.0 { # Sampling of DImode arithmetic used by (at least) i386 and m68k. __divdi3 __moddi3 __udivdi3 __umoddi3 Now ld complains when linking shared c++ libs :-(. Now, what can we do? Can I use GLIBC_2.1 as a version in glibc instead? Or maybe even a special GLIBC_COMPAT? Franz.
