Bug report

Bug description:

Working from this #130913 PR, I recently needed to add this line #include <sys/sysctl.h> // sysctlbyname in a header file.

From CI, the check-c-globals.py tools failed with this message:

..... ..... /home/runner/work/cpython/cpython/Modules/_multiprocessing/semaphore_macosx.h:5:10: fatal error: sys/sysctl.h: No such file or directory
    5 | #include <sys/sysctl.h>  // sysctlbyname
      |          ^~~~~~~~~~~~~~
compilation terminated.
# requested file: </home/runner/work/cpython/cpython/Modules/_multiprocessing/semaphore_macosx.h>

Did this not work:

Occasionally the tool is unable to parse updated code.
If this happens then add the file to the "EXCLUDED" list
in Tools/c-analyzer/cpython/_parser.py and create a new
issue for fixing the tool (and CC ericsnowcurrently
on the issue).

Ah it also mentions the issue, sorry.

I guess if the PR is approved, this new file will be noted as exluded from the tool run.

I added in Tools/c-analyzer/cpython/_parser.py the file that raises the error.

# XXX Handle these.
EXCLUDED = format_conf_lines([
    # macOS
    'Modules/_scproxy.c',              # SystemConfiguration/SystemConfiguration.h
    'Modules/_multiprocessing/semaphore_macosx.h',              # <sys/sysctl.h>

    # Windows

I created a new branch with the change into the Tools/c-analyzer/cpython/_parser.py file but the "Check for unsupported C global variables" test is disabled - see https://github.com/YvesDup/cpython/actions/runs/27023166717/job/79756266970
