the codeblocks-17.12mingw-setup.exe came with Mingw 5.1.0 version.
but maybe you have right... the Code Blocks came with 64 bits?
"At least not of TDM-MinGW, and thats the compiler they are currently using to build CodeBlocks."
yes... the 7.2.0 it's from GNU, i think.. thank you so much for the correction
