Negative. I had to explore the internals manual. I found out that, for 
executable formats not supporting initialization sections, __main calls the 
constructors for static C++ objects at startup, and the destructors before 
shutdown. I knew of this requirement for static CRTs (I read an article of 
Pietrek on MSDN Magazine on rolling your own CRT), but GCC is the only 
compiler I know of that inserts an explicit call to the initializator, 
instead of simply doing the initialization before calling main()

That's what I did. But this doesn't make the problem go away: sometime in 
the future, we'll need to provide a static CRT for POSIX+ programs. I'll 
try to add -lgcc, like the documents suggest, and implement atexit() in 
psxdll. That should do the trick

We're not talking about Borland C
