Setting STARTUP_WITH_SHELL to 0 in inferior.h means that gdb segfaults when
trying to run a program with arguments. This is because of the code:
- cp = strchr (cp, ' ');
- if (cp == NULL)
- cp = strchr (cp, '\t');
- if (cp == NULL)
- cp = strchr (cp, '\n');
Which is clearly broken. While google I found a post which suggests this
problem has been there since at least 5.3 !!!. I will attach a suggested patch.

I looked briefly at this patch. Instead of using strchr I think
it should just use an ordinary loop looking for the next separator.
