Description of problem:

Hello there,

I just tried to compile package busybox-0.60.2-7 from Redhat 8.0.

Here are some of the compiler messages.

md5sum.c:446: warning: operation on `temp' may be undefined
md5sum.c:454: warning: operation on `temp' may be undefined
md5sum.c:461: warning: operation on `temp' may be undefined
md5sum.c:468: warning: operation on `temp' may be undefined
sed.c:427: warning: operation on `idx' may be undefined

Here is a patch which fixes the messages.
