passing command-line arguments, still

[I sent this to gcc-help by mistake. I'm reposting it here in case
anyone has a suggestion. I did take dje's advice, and deleted the build
directory, except that I preserved config.status and regenerated
Makefile. The observed behavior remains unchanged. TIA.]

My first question regards command-line options. I've had no trouble
defining switches (-f-foo), but no luck defining an option that takes
an argument. The latter are accepted by gcobol and not passed to
cobol1.
In cobol/lang.opt, I have:
indicator-column
Cobol Joined Separate UInteger Var(indicator_column) Init(0)
IntegerRange(0, 8) -indicator-column=<n> Column after which
Region B begins
strace(1) shows the problem:
[pid 683008] execve("../../../build/gcc/gcobol",
["../../../build/gcc/gcobol", "-main", "-o", "obj/SG105A", "-B",
"../../../build/gcc/", "-f-flex-debug", "-f-yacc-debug",
"-indicator-column", "1", "cbl/SG105A.cbl", "-lgcobol", "-lm", "-ldl"],
0x55a19b487940 /* 36 vars */ <unfinished ...>
gcobol is being invoked with 3 options used by cobol1:
"-f-flex-debug", "-f-yacc-debug", "-indicator-column", "1"
where -indicator-column takes an argument, "1". But it's not passed to
cobol1:
[pid 683008] <... execve resumed>) = 0
[pid 683009] execve("../../../build/gcc/cobol1",
["../../../build/gcc/cobol1", "cbl/SG105A.cbl", "-quiet", "-dumpbase",
"SG105A.cbl", "-main", "-mtune=generic", "-march=x86-64", "-auxbase",
"SG105A", "-f-flex-debug", "-f-yacc-debug", "-o", "/tmp/ccIBQZv1.s"],
0x1578290 /* 40 vars */ <unfinished ...>
The stanza in cobol/lang.opt looks similar to others in
fortran/lang.opt. The gcc internals don't mention anything else that I
could find that needs to be done. I've done a complete rebuild after
"make distclean". And still no joy.
We are working with a gcc fork of 10.2. Our log message says (in part):
The "tiny" branch was started with the 10.2.1
origin/releases/gcc-10 branch> c806314b32987096d79de21e72dc0cf783e51d57)
What am I missing, please?
