This was discussed and fixed in Gnulib a few months ago [1]. I assume
you are using g++ 15 and the others are not.
Here are the relevant commits:
$ git branch --contains=7ee6e40b6730c87e5c1323bb5c2564bcb6eff9e4
* master
stable-202507
$ git branch --contains=e331531a771443edae4135e6bcd016282cf1a3aa
* master
stable-202507
But groff is using a branch that does not contain them:
commit e3ff929ddea95e0fc9fe7ea3541d28665de42370

gnulib: Update stable/2025-01 branch.
...to commit 3fbc2c7bb3, 3 March.
Using the following command I can make ./bootstrap use the master branch
from my local checkout to copy files:
$ env GNULIB_SRCDIR=$HOME/.local/src/gnulib ./bootstrap
Allows me to build groff fine with g++ 15.
