I got the very latest git head, and tried to compile.
But, with ./configure's run, I got an error message as follows;

I installed opencv 3.2.0 last December. So, I suspected the configure
With the configure script of 21th Mar, the compilation ended without
any problem.

I checked the difference of 2 configure scripts, but I can't find the
change which cause the problem.
