To make things clear: "Active maintainer" means to make sure any new
version of gnulib runs perfectly on the system.  I can't do that, but
I can send small patches to fix problems with SunOS that I apply anyway
to get certain packages using gnulib running for me, like grep.  Where
can I send such patches?

So far, it did not take much for grep, m4 and gawk.  Some examples:

Otherwise size_t is not declared.  Then it would help an awful lot if
the check for a missing memmove could be put back in, along with memmove
itself.

A slightly more complicated issue is in src/dfa.c.  The is* functions are
used, but they are macros on SunOS4 and if you undefine them (which is
not the case in src/dfa.c), you find there are no functions of the same
name in libc.  In fact I am used to that from other older systems as well,
so making that more portable would be useful for others, too.

As for the meaning of SunOS 4: It is best described by hack value. :-)
