If I understand it correctly, the AC_CHECK_FUNCS macro is redundant,
so we can eliminate it.
We have to set ac_cv_func_getmntent and HAVE_GETMNTENT, for
compatibility reasons, but we eliminate one compilation.

If there are no objections, I'll install the following patch a few weeks
after the 2.60 release, when all the guys from TIME and CNN will allow
Ralf to get some sleep again.

Have a nice day,
        Stepan
