----------------------------------------
The Ruby is compiled by MinGW64 (GCC 4.7.0 ), configure script is :

./configure --build=x86_64-w64-mingw32 CFLAGS="-O2 -mieee-fp -I/usr/local/include" LDFLAGS="-L/usr/local/include"

when miniruby executing, error occurs with the following message:


        CC = gcc
        LD = ld
        LDSHARED = gcc -shared
        CFLAGS = -O2 -mieee-fp -I/usr/local/include
        XCFLAGS = -include ruby/config.h -include ruby/missing.h -fvisibility=hi

        CPPFLAGS =   -I. -I.ext/include/x64-mingw32 -I./include -I.
