They were introduced through use of "$RPM_OPT_FLAGS" in the
specfile. The intention is to make code more robust against
attacks, and therefore the security team of SUSE set them
in the global rpm macros file.

I'm sure about to use options "-D_FORTIFY_SOURCE=2 -fstack-protector",
but unsure about the other two on older systems.

I think David Shaw already explained, that the issues don't occur
anymore, when using "-O1" instead of "-O2" for comilation of
rijndael.c.

I changed it as suggested (only compiled rijndael.o), and the issues
were really gone. I therefore filed a new bugzilla entry against gcc:
	https://bugzilla.novell.com/show_bug.cgi?id=459921

The bad news is, that profiling the code is no longer possible, when
mixing "-O1" with "-O2" object files. But hopefully the compiler
specialists can find the cause and fix it.

Thanks!

Best regards,
	Klaus.
