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,
