Bug#812058: Fix for the gargoyle-free FTBFS

[Adrian Bunk]

Control: tags -1 patch

What broke the build is that gcc 6 changed the default C++ standard
from C++98 to C++14.

Not all valid C++98 code is also valid C++11 and C++14 code.

Note that this just changed the default, when told to process C++98 code 
gcc 6 does not differ in any significant way from gcc 5.

Making the code compatible with C++14 would be the best possible 
solution, but as a workaround it is possible to fix the build with
this change to tell gcc that this is C++98 code.

I am aware that this change results in a (harmless) compiler warning on 
every compiled C file. The build system of the package uses the same 
CFLAGS for both C and C++ code.

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.
