Bug ID: 125987
Summary: gcobol --help for -no_main doesn't agree with
implementation (which provides -nomain)
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: cobol
Assignee: unassigned at gcc dot gnu.org
Reporter: peeterjoot at protonmail dot com
Target Milestone: ---
Running gcobol version:
```bash
# /opt/gcc-trunk-20260606/bin/gcobol --version
gcobol (GCC) 17.0.0 20260604 (experimental)

The --help output shows:
```bash
# /opt/gcc-trunk-20260606/bin/gcobol --help 2>&1 | grep -A5 -e -main
-main option uses the first PROGRAM of filename as the entry point for
the main() procedure.
-no_main
means that there is no -main, and the main() entry point is
provided by some other compilation or .o file
```
but that doesn't match the implementation:
```bash
# cat FOO.cob
IDENTIFICATION DIVISION.
PROGRAM-ID. FOO.
DATA DIVISION.
WORKING-STORAGE SECTION.
LINKAGE SECTION.
PROCEDURE DIVISION.
GOBACK
.
# /opt/gcc-trunk-20260606/bin/gcobol -c -no_main FOO.cob
gcobol: error: unrecognized command-line option ‘-no_main’; did you mean
‘-nomain’?
# /opt/gcc-trunk-20260606/bin/gcobol -c -nomain FOO.cob
# # okay.
```
