Looks indeed like we should change the code, since swprintf(wchar_t*, wchar_t*) isnt' compliant to the latest C standards (at least that's what http://www.cplusplus.com/forum/general/6612/ suggests).

Anyhow, qprocess_win.cpp compiles fine for me with both mingw-builds-32-4.7.2-posix-sjlj-rev1, mingw-builds-64-4.7.2-posix-sjlj-rev1, a stock mingw.org  , tdm64-gcc-4.7.1-3.exe and finally a recent build from RubenV . Which toolchain / version of MinGW-w64 are you using?
