This code is included in the build tools makemapdata and genmap, and it
expects that libc exposes a definition of u_char. But u_char is not
defined in either C or POSIX standards, and some systems don't have it.
Namely this breaks the build on hosts using musl libc, because musl only
exposes u_char if _GNU_SOURCE is defined.

Content is unchanged compared to v1, but hopefully the patch is not
corrupted this time and I added a cc: stable
