-fvisibility=hidden is the culprit; FLTK started using it this summer.
Building with -fvisibility-inlines-hidden instead seems to avoid this.

Although we'll get smaller binaries with -fvisibility=hidden,
I'm inclined to forcibly switch it to -fvisibility-inlines-hidden.
It would also be possible to do some prodding, by running
make && rm src/Fl.o && \
sed -e 's/fvisibility=hidden/fvisibility-inlines-hidden/g' -i makeinclude && \
make || return 1

which builds only the one file where it's relevant with less aggressive
visibility settings.

Considering that I'd be using the same sed to disable it globally or for
the one file, I might as well set it for only the one file.
