Splint 3.1.2 --- 26 Dec 2015

dms2deg.c:36: Include file <unistd.h> matches the name of a POSIX library, but
    the POSIX library is not being used.  Consider using +posixlib or
    +posixstrictlib to select the POSIX library, or -warnposix to suppress this
    message.
  Header name matches a POSIX header, but the POSIX library is not selected.
  (Use -warnposixheaders to inhibit warning)
dms2deg.c:47:6: Function main declared to return void, should return int
  The function main does not match the expected type. (Use -maintype to inhibit
  warning)
dms2deg.c: (in function main)
dms2deg.c:58:8: Variable in shadows outer declaration
  An outer declaration is shadowed by the local declaration. (Use -shadow to
  inhibit warning)
   gnis.h:159:7: Previous definition of in: FILE *
dms2deg.c:87:6: Test expression for if not boolean, type int: error
  Test expression type is not boolean or int. (Use -predboolint to inhibit
  warning)
dms2deg.c:99:39: Array element where[0] used before definition
  An rvalue is used that may not be initialized to a value on some execution
  path. (Use -usedef to inhibit warning)
dms2deg.c:104:6: Test expression for if not boolean, type int: vopt
dms2deg.c:58:8: Variable in declared but not used
  A variable is declared but never used. Use /*@unused@*/ in front of
  declaration to suppress message. (Use -varuse to inhibit warning)
