Not all projects compile well.
I still don't know why.
I have a project with 306 source files and it hangs when it compiles the 17th file.
I have other projects larger than that, in number of lines, with 148 files, and it builds well.
It happens under CrossOver Linux 7.1 and CrossOver Games Linux 7.2 demo.
To-do: create a new project and then add the files manually. I suspect the project with problem is an old project that came from older versions of Borland C++. Let's see what happens.
