SYSCF/PANICLOG fix (trunk only)

     files.c wouldn't compile if SYSCF was defined and PANICLOG wasn't.
Also, a couple of PANICLOG option sanity checks treated 0 as an error
but then said that the value had to be 0, 1, or 2.  I went with the
message and changed it to treat 0 as ok.  Unfortunately the numeric
value is derived via atoi() so you get 0 from bogus input.  Perhaps it
should use sscanf(string,"%d%c",&number,&dummy)==1 to try harder to make
sure it actually gets a number.
