never used / never referenced

compiled GNU Go 3.7.8 with icc 9.0 (intel) with high verbosity (-w2) It gives some curious remarks about unused variables, notably in owl_defendpat.c

getopt.c(382): remark 869: parameter "argc" was never referenced

int argc;

getopt.c(383): remark 869: parameter "argv" was never referenced

char *const *argv;

--

fuseki.c(288): remark 593: variable "best_fuseki_value" was set but never used

int best_fuseki_value;

--

reading.c(1636): remark 593: variable "other" was set but never used

int color, other;

--

owl_defendpat.c(6453): remark 593: variable "a" was set but never used

int a, b;

owl_defendpat.c(6466): remark 593: variable "a" was set but never used

int a, b;

--

gmp.c(240): remark 593: variable "d0" was set but never used

FD_ZERO(&readReady);

gmp.c(240): remark 593: variable "d1" was set but never used

FD_ZERO(&readReady);

This file is borrowed. We won't touch it unless it causes actual failures.

fuseki.c(288): remark 593: variable "best_fuseki_value" was set but never used
    int best_fuseki_value;
        ^

reading.c(1636): remark 593: variable "other" was set but never used
    int color, other;
               ^

I have fixed these in a maintenance patch under preparation.

owl_defendpat.c(6453): remark 593: variable "a" was set but never used
    int a, b;
        ^

owl_defendpat.c(6466): remark 593: variable "a" was set but never used
    int a, b;
        ^

This is in generated code and doubtful it's worth the extra complexity in the generating program to avoid it.

gmp.c(240): remark 593: variable "__d0" was set but never used
      FD_ZERO(&readReady);
      ^

gmp.c(240): remark 593: variable "__d1" was set but never used
      FD_ZERO(&readReady);
      ^

Also borrowed code.

Let's just close this as wontfix.
