Description

dragonfly/lib/libalias/alias_db.c:857]: (style) Variable 'icount' is modified but its new value is never used.
[dragonfly/lib/libalias/alias_proxy.c:667]: (warning) sscanf() without field width limits can crash with huge input data.
[dragonfly/lib/libalias/alias_proxy.c:738]: (warning) sscanf() without field width limits can crash with huge input data.

The first one looks like a simple unused local variable.

The next two look like buffer sizes need to go into %s specifiers.

No bugs here. I removed the unused variable from alias_db.c. The sscanf()s in alias_proxy.c are constrained by the input buffer size and cannot overflow.
