Actually, it's declared in three files: errno.h, stdlib.h and stddef.h.  
mars.c uses only the last two.

Why should _MT be enabled? There is no -D_MT in win32.mak. Are we using  
different makefiles?

root/async.c sets _MT explicitly, but the example at hand is from mars.c.

If I add -D_MT to CFLAGS in the makefile, I still get a lot of  
differences. The first difference is now one in a function's  
prologue/epilogue - the binary from the .zip saves/restores the ECX  
register, while my binary doesn't. The functions are otherwise identical.
