I tried this, it didn't really help; I believe libgcc is a gcc
runtime; there is no solaris libgcc, just solaris libc.
However, in the process of messing around with that idea, I tried
gsed -i 's/strlen/zstrlen/g' src/ctlib/*.c
Which (amazingly) allows the whole thing to compiled (zstrlen is any
random symbol name, not some replacement defined somewhere). That may
not help much, but it does mean the problem is specific to strlen().
After installing, I even succeeded in compiling DBD::Sybase with:
SYBASE=/usr/local perl Makefile.PL &&
make CC='gcc -m64' LD='gcc -m64' OPTIMIZE=-O3 CCCDLFLAGS='-fPIC'
I nuked the TDS src dir for further testing; running James' ld command
without "-lc -lsocket -lnsl" confirms the above: many libc functions
are shown as undefined, but only strlen says "(symbol scope specifies
