Hi guys, It is said that MinGW is not supported by Boost because it is not fully POSIX compatible: http://www.boost.org/doc/libs/1_55_0/more/getting_started/windows.html#pch Excerpt: "A note to Cygwin and MinGW users If you plan to use your tools from the Windows command prompt, you're in the right place. If you plan to build from the Cygwin bash shell, you're actually running on a POSIX platform and should follow the instructions for getting started on Unix variants. Other command shells, such as MinGW's MSYS, are not supported-they may or may not work." Does it mean that is some program that uses Boost was compiled with MinGW, then it can randomly crash or has some stability issues? Thanks in advace, --- Kosta
