For example, variable length arrays and the "inline" keyword are both
flagged by the compiler as an extension and gnulib and gettext bit use
them heavily. Without this patch, my builds on travis are failing
because the output logs are > 4MB.

At the risk of starting another fight, can we move to C99 as the
standard? The only major compiler I know of that doesn't support it is
MSVC. But do we really need to stay so much behind times to support
MSVC? Windows users can use CygWin / MingW to compile Wget. Half of
gnulib, gettext or other libraries will probably not compile properly
using MSVC anyways. Microsoft is not keen on improving their support
for C runtimes.

Is there anything else that I'm missing?
