Re: [PATCH] Use multi-arch'd START_INFERIOR_TRAPS_EXPECTED on Alphatarget

Hmm, HP merge.  An intermediate version looked like:

   /* If STARTUP_WITH_SHELL is set, GDB's "run"
!  * will attempts to start up the debugee under a shell.
!  * This is in order for argument-expansion to occur. E.g.,
!  * (gdb) run *
!  * The "*" gets expanded by the shell into a list of files.
!  * While this is a nice feature, it turns out to interact badly
!  * with some of the catch-fork/catch-exec features we have added.
!  * In particular, if the shell does any fork/exec's before
!  * the exec of the target program, that can confuse GDB.
!  * To disable this feature, set STARTUP_WITH_SHELL to 0.
!  * To enable this feature, set STARTUP_WITH_SHELL to 1.
!  * The catch-exec traps expected during start-up will
!  * be 1 if target is not started up with a shell, 2 if it is.
!  * - RT
!  */
   #define STARTUP_WITH_SHELL 1
- #define START_INFERIOR_TRAPS_EXPECTED (STARTUP_WITH_SHELL + 1)

Does STARTUP_WITH_SHELL need to be multi-arched?

I'm wondering if it would be better to make it a variable (``set 
startup-with-shell <boolean>'').  Looking at its uses it appears that 
fork-child.c:startup_inferior() would still work (if it did previously).
