Thanks for the suggestion. But that's only one small piece of support of
Minix in gnulib. If one wants to go for it seriously, the first step is
to update the documentation, and the second step is to make gnulib-tool
generated testdirs compile fine.


For the first step, I've updated the platforms x symbols matrix at
  http://www.haible.de/bruno/gnu/various-symlists.tar.gz
and added documentation:

        Documentation about Minix.
        * doc/posix-headers/*.texi: Add info about Minix 3.1.8.
        * doc/glibc-headers/*.texi: Likewise.
        * doc/posix-functions/*.texi: Likewise.
        * doc/glibc-functions/*.texi: Likewise.
