This is just a fiberized rand() test I put together for the WINE devs after observing a difference in behavior vs. Win7. The associated bug is: https://bugs.winehq.org/show_bug.cgi?id=46273 To build you must first have checked out the submodules recursively: `git submodule update --init --recursive` Then steps using mingw to build the 32-bit windows exe in GNU/Linux: ./bootstrap mkdir build cd build ../configure --host=i686-w64-mingw32 make file src/randtest.exe To build a linux binary without mingw, omit the --host=i686-w64-mingw32. To build a 64-bit windows exe, use --host=x86_64-w64-mingw32. Just in caes, these are the mingw packages I have installed under debian 9.5: ii binutils-mingw-w64-i686 2.28-5+7.4+b4 amd64 Cross-binutils for Win32 (x86) using MinGW-w64 ii binutils-mingw-w64-x86-64 2.28-5+7.4+b4 amd64 Cross-binutils for Win64 (x64) using MinGW-w64 ii g++-mingw-w64 6.3.0-14+19.3 all GNU C++ compiler for MinGW-w64 ii g++-mingw-w64-i686 6.3.0-18+19.3+b3 amd64 GNU C++ compiler for MinGW-w64 targeting Win32 ii g++-mingw-w64-x86-64 6.3.0-18+19.3+b3 amd64 GNU C++ compiler for MinGW-w64 targeting Win64 ii gcc-mingw-w64 6.3.0-14+19.3 all GNU C compiler for MinGW-w64 ii gcc-mingw-w64-base 6.3.0-18+19.3+b3 amd64 GNU Compiler Collection for MinGW-w64 (base package) ii gcc-mingw-w64-i686 6.3.0-18+19.3+b3 amd64 GNU C compiler for MinGW-w64 targeting Win32 ii gcc-mingw-w64-x86-64 6.3.0-18+19.3+b3 amd64 GNU C compiler for MinGW-w64 targeting Win64 ii mingw-w64 5.0.1-1 all Development environment targeting 32- and 64-bit Windows ii mingw-w64-common 5.0.1-1 all Common files for Mingw-w64 ii mingw-w64-i686-dev 5.0.1-1 all Development files for MinGW-w64 targeting Win32 ii mingw-w64-tools 5.0.1-1 amd64 Development tools for 32- and 64-bit Windows ii mingw-w64-x86-64-dev 5.0.1-1 all Development files for MinGW-w64 targeting Win64
