Fine, this weekend I should have some time to fix small bugs in therion. So 
If you have more of them, please mail me them. I'll also check warnings, 
that Wookey sent to me.

Of course :)

You're right. I'll check, whether I mix unsigned and signed chars somwhere 
else. And I'll try to change it.

This is why I recommanded you to compile included getopt C code (in extern 
directory, it's done via make config-macosx). If it didn't help, the 
problem is probably not the getopt version...

The other idea: May be, I'm combining C and C++ code the wrong way (I just 
link .o files created by C and C++ compilers together). May be, it's not 
correct. I have no idea. I've studied mathematics, not computer 
programming... :(
