in thread Using STDIN after exec() with ActiveState Perl

Oh indeed you're right, actually it's not for the PATH environment variable that I needed the exec. It's for another environment variable which is used by the C++ library. If I set it with %ENV and I don't use exec, then the C++ library doesn't see it.

Which one? :)

    It's the unitsync library used by the Spring RTS project (https://springrts.com/). The environment variables used by this library are specific to this project (SPRING_DATADIR and SPRING_WRITEDIR).
      It should work exactly the same way
      use Module::Load; ... $ENV{SPRING_DATADIR} = ...; load( "ModuleName" );
        On Linux it works, but not on Windows (I re-checked right now).
