Bug ID: 193471
Summary: Mismatched variable type in md5(1) from getopt
Product: Base System
Version: 10.0-STABLE
Hardware: Any
OS: Any
Status: Needs Triage
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: freebsd-bugs at FreeBSD.org
Reporter: webpages at sprow.co.uk
The optarg from getopt(3) is defined as a char *, but md5 variable
'checkAgainst' is an unsigned type which leads to a warning on assignment and
later calls to strcmp (et al) when using a strict type check compiler.
Also, the variables may as well be static scope, as per the following patch
against SVN revision 238964 of /sbin/md5/md5.c
