Need PRI_LL_PREFIX in Ruby 1.9.3 P286
Here is my configuration using MinGW6 with MSYS
./configure --build=x86_64-w64-mingw32 CFLAGS="-O3 -finline-functions -I/usr/local/include -I/mingw/mingw/include -D__USE_MINGW_ANSI_STDIO" LDFLAGS="-L/usr/local/lib"
but found the #define PRI_LL_PREFIX "ll" exists in P194, but missing in P286. That cause several file compiled failed in P286.
add the define in the config.h , the compile can be continued
