[bug-gperf] new gperf release?

[Bruno Haible]

Hi Eric, Marcel,

The last gperf release (3.0.4) was in 2009. Meanwhile a few reports have
been coming in about wrong generated code (it produces link errors when compiled
with gcc -O0):
  https://savannah.gnu.org/bugs/?37071
  https://savannah.gnu.org/patch/?7383

All open entries in the bug tracker, the patch tracker, and the support tracker
have been handled, and all open mails to the mailing list have been answered,
except for those from Denis Naumov in
http://lists.gnu.org/archive/html/bug-gperf/2013-03/threads.html .

Therefore I would suggest to make a new release. Only you can, since I'm not
registered as an official maintainer any more since 2012.

I've set the version number to 3.1, because the generated functions now have
different signatures:
  The 'len' parameter of the hash function and of the lookup function is now
  of type 'size_t' instead of 'unsigned int'. This makes it safe to call these
  functions with strings of length > 4 GB, on 64-bit machines.

The procedure for creating a tarball is:
  ./configure
  make
  make dist

Feel free to announce a pretest before making a release.

Bruno
