This is still more then single variable ... Anyway, look at configure flags for basic libc in debian/sysdeps/i386.mk: libc_extra_config_options = $(extra_config_options) --with-tls --without-__thread It doesn't use TLS internally, there is no .tbss ot .tdata segment in libc.so. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
