I guess it's probably errno 22:

     22 EINVAL Invalid argument.  Some invalid argument was supplied.  (For
             example, specifying an undefined signal to a signal(3) function
             or a kill(2) system call).

Something in the object module is confusing GCC.

Because it finds out that they've terminated when it performs a wait() system
call, and it does that after running a command.

Because Linux is not an operating system. It's a kernel. A Linux distribution
is a Linux kernel and a collection of packages, and it's up to the distribution
to decide what packages are there and where they go.

Why do you care where tcsh is anyway?
