I've added printf dump to _open() and it gets triggered all over the
place like this:
---
_open() failed:
filename = c:/devel/djgpp/tmp/fxincaaa
oflag = 0
DOS error code = 2
---
Also common is a failure with oflag = 0x901. However none of this is
related to the particular issue I'm trying to debug and it's very
common, so I guess it's expected (Well, I wish printf() debugging
had a stack backtrace...)

Now about that particular failure:
_shell_command() from system.c does:

    char *atfile = (char *) alloca (L_tmpnam);
    errno = 0;
    respf = fopen (tmpnam (atfile), "wb");
    if (respf)
    {
      ...
    }
    else
       return emiterror ("Cannot open script file for $SHELL", errno);

Now that fopen(...) call fails _open() like this:
---
_open() failed:
filename = c:/devel/djgpp/tmp/dj410000
oflag = 901
DOS error code = 5
---

I've checked with RBIL and see that 0x05 is, well, 'access denied'.
How comes? Any pointers?
