Since 1) affects guile and physfs themselves (not just the test 
programs), it probably merits the same classification as 2) for upstream 
notification. Rather than introducing -Wno-unused-but-set-variable 
though, they should probably clean up the offending code.

Would you like to share this letter-writing campaign and contact group 
1) (guile, physfs) and 3) (exiv2, xine-lib). I'll contact 2) fltk, 
libdnet, winpcap, xvidcore.
