[tlbuild] [mp-implementors] metapost-1.200: getline clash

[Karl Berry]

    It looks like this is because POSIX 2008's getline() is now exported
    by default in the newer glibc versions (as of 2.9.90, apparently).

Damn POSIX.  Damn glibc.

It seems mft, *tangle (apparently including luatangle), and *weave are
the programs which end up with a getline (get_line in the Pascal web
world).  I tried to fix it as follows.  It still compiles for me, but I
don't have any access to a system running such a newly
broken^H^H^H^H^H^Himproved setup, so can you please try it?

Thanks,
Karl
