X-Debbugs-Cc: fmtlib@packages.debian.org, aron@debian.org

Dear maintainers,

We are planning the transition towards fmtlib 11.1 (in experimental).
You package nmodl 0.6-2 FTBFS with fmtlib 11.1.1+ds1-1.

There are no significant API changes from (in testing) fmtlib 10 to 11.
After a quick look at ratt logs (thanks @aron for running it), I can
spot problems including (but not limited to):

- removal of APIs: nmodl, opm-common
- use of private APIs (fmt::detail): dolphin-emu
- '-fpermissive' compiler errors: doxygen, nheko
- unformattable types: genomicsdb, gerbera
- missing #include for std header: ntfs2btrfs, transmission

...and many of them have already been fixed by upstream.

There might be false positives due to collision with other on-going
transitions (e.g. python3.13). Please close this bug if so.
