DOS/Windows-specific code: cli-cmds.c

[Eli Zaretskii <eliz at is dot elta dot co dot il>]

    * cli-cmds.c:

    /* FIXME: this should be auto-configured!  */
    #ifdef __MSDOS__
    # define CANT_FORK
    #endif

This seems to cry for either an Autoconf test (based on whether the
compiler defines __MSDOS__ or not) or perhaps the whole snippet should
be moved to config/i386/xm-go32.h.


    * cli-cmds.c:shell_escape()

    #ifdef __DJGPP__
      /* Make sure to return to the directory GDB thinks it is, in case the
	 shell command we just ran changed it.  */
      chdir (current_directory);
    #endif

This code is there because the current working directory is a global
notion (as opposed to being private to each process on Posix
systems).  Windows ports, at least the non-Cygwin ones, probably want
this as well.  Suggestions how to test this, anyone?  Should we define
a GLOBAL_CURDIR macro (zero by default)?
