[xml/sgml-pkgs] Bug#551079: libexpat1: links with -lpthread for no reason

[Raphael Bossek]

Hi all,

background of the -lpthread -D_REENTRANT request was bug#275097 I can
not remember for all side effects anymore but maybe Mirko can help
testing if the change works with the latest 4suite and expat versions.

Mirko, are you working with 4Suite and mod_python/Apache and can help
us with the change ?

Regards,
Raphael
