Hi!  When trying to upgrade package `transfig 3.2.5e` from Guix commit
`404f6953` to that of commit `4a943cfd`, the build fails showing many
instances of warnings like the ones below, and finally the error at the
bottom:

```

```

Maybe some new version of the compiler got more picky with some deprecations?
I'm attaching the whole
`/var/log/guix/drvs/2x/m0s1604xx2wfzj8swza7jm6s94nz1l-transfig-3.2.5e.drv.bz2`.

Thanks a lot!
