Goodness. I don't think I've seen a C++ compiler complain on that
sort of stuff. Then again, most of us are compiling with gcc/g++.

The configure script is generated by the autoconf package:

The "variable" is part of the AC_C_CONST macro. The script couldn't
figure out how to get your compiler to use const and so it tried to
hack it. To see the test program that it used, check config.log
