       "Is there not promise of rain?" Ling Tan asked suddenly out
        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.

Description: Build with -std=gnu++98
 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.
 .
 The CXXFLAGS handling in configure.in is wrong and prevents passing
 flags the normal way, as a workaround this patches configure.in
