Usertags: unblock
Please unblock package jumpnbump
jumpnbump 1.61-3 and below crash when the player jumps and sound is enabled
(the default) on systems where type char is unsigned (e.g. arm* powerpc*).
This is due to passing -1 to a parameter of type char wich then wraps to
255 causing an out of bounds array reference.
Unless the player knows this is a sound issue and knows how to disable sound
this renders the game unplayable on those architectures.
The fix for the issue is trivial and has been accepted upstream. It simply
consists of changing the parameter type from char to signed char.
unblock jumpnbump/1.61-3.1
