A situation that probaly won't apply ever, static bash is big. a static
backend+profile(s) are probaly as big as a 2MB static bash binary.
Backend is relatively dumb and therefore can be small I'd think. Would
fit better on small media (floppy disk). Then again, how one would run a
configure script without bash beats me too, so like I said, this is a
situation that most likely won't ever apply.
On the other hand, if the C program doens't run a shell to run make, but
have it run make directly, it would mean one less process running (and
not running a 2 MB bash can be a nice saving on a system with limited
ram). Again, if a 2 mb bash binary slows down your system a lot you dont
have a great fast system anyways, so you won't notice the difference
really. It still has to go compiling which requires far more then a bash
process (then again, static gcc is 500 KB or so).
