This patch is needed to allow builds with newer versions of the GNU libc (2.16+). commit 66712c23388e93e5c518ebc8515140fa0c807348 Author: Eric Blake Date: Thu Mar 29 13:30:41 2012 -0600 stdio: don't assume gets any more Gnulib intentionally does not have a gets module, and now that C11 and glibc have dropped it, we should be more proactive about warning any user on a platform that still has a declaration of this dangerous interface. * m4/stdio_h.m4 (gl_STDIO_H, gl_STDIO_H_DEFAULTS): Drop gets support. * modules/stdio (Makefile.am): Likewise. * lib/stdio-read.c (gets): Likewise. * tests/test-stdio-c++.cc: Likewise. * m4/warn-on-use.m4 (gl_WARN_ON_USE_PREPARE): Fix comment. * lib/stdio.in.h (gets): Make warning occur in more places. * doc/posix-functions/gets.texi (gets): Update documentation.

# Hydrilla&Haketilo website

This is the code used by Haketilo website. A live version of the website can be
seen at [https://haketilo.koszko.org](https://haketilo.koszko.org). There you
can also find more information about Haketilo itself - a tool to modify pages
opened in a web browser.

## Hacking

At the moment the recommended method of hacking on the website code is through
the [GNU Guix](https://guix.gnu.org/) package manager.

A Guix version of at least 1.1.0 is expected. Most development tasks have been
automated through Makefile. Rules use the `guix time-machine` command under the
hood to pull and run a fixed Guix version that is known to work with the
code. Please look into the Makefile to see what rules are available.
