I think it is fine to leave the switch in options.cc.  Just updating the
documentation should suffice, no bothering of users.

Apparently Fritz implemented -fdec-math in r7-3677-g8e8c2744faa0cf, and
this part of code was rewritten later.

Jerry or myself can do the commit later.

Looking at my addition again, I think that this change to invoke.texi:

"... These functions are now GNU extensions."

should correctly read: "These functions are now either part of Fortran 2023
or GNU extensions."

Note to myself to fix this.=
