Now time for next level of confusion - your patch touches bootstrap.sh but I don't really know how to execute it. Running it directly as "bootstrap.sh" obviously does not work, and I don't see any "sh" binary for "sh bootstrap.sh" to work.
It has to be run in MSYS, as I explained at http://nuwen.net/mingw.html#build . Here are slightly more detailed instructions: 0. You're running x86, so you need 7-Zip's x86 7za.exe, which I removed between distro 10.3 and 10.4. Instead of downgrading to distro 10.3, you can download it from http://www.7-zip.org/download.html . It's the "7-Zip Command Line Version". Just put 7za.exe in C:\MinGW\bin, it's a stand-alone executable. 1. Download http://nuwen.net/files/mingw/msys-10.4.7z 2. Extract it. 3. Run my extract.bat (it's a one-liner). 4. Run msys.bat to launch MSYS. 5. See C:\MinGW\scripts-10.4\boost.sh for my Boost build script (the patches I use are also in that directory). WARNING: Read my "Important notes" in #build, which explain the directory assumptions. In particular, you should "run" my build script by copying and pasting one line at a time into MSYS and carefully watching the output. STL P.S. x86 is dead! :->
