>Description:
Updating QEMU in 2026Q1 now brings in gcc12 as an indirect dependency.
This is ultimately due to FFTW now having a _run-time_ dependency on
gfortran:

https://github.com/NetBSD/pkgsrc/blob/trunk/math/fftw/options.mk#L5

and:

https://github.com/NetBSD/pkgsrc/blob/trunk/math/fftw/options.mk#L40

I don't see why it isn't just a build-time requirement to have a
FORTRAN compiler to get FFI right?

>How-To-Repeat:
Update to 2026Q1 and watch QEMU bringing in gcc12. Whoo-hoo!
>Fix:
pkgsrc magic reqd.
