Excellent. Two questions: How did you manage that libc_r was
used? And do you see any possibility for me to detect
automatically, whether libc or libc_r should be used?

Excellent again. Here's how to go:
- Create a new version of DBD::mysql be doing a
perl Makefile.PL --static --config OPTIMIZE=-g LINKTYPE=static
make
make perl
make test
- Start it from within gdb by doing
cd mysql
gdb ../perl
r -I../blib/arch -I../blib/lib t/00base.t
(Replace the test script name, as appropriate.)
Feel free to ask for more suggestions.
Bye,
Jochen
