Bash 5.1: accept loadable build fix

[Marc Aurèle La France]

typemax.h states it should be included after config.h, limits.h, stdint.h, 
and inttypes.h.  But, on my system (with glibc 2.32), accept.c ends up 
including <limits.h> after typemax.h, via the sequence ...

accept.c -> loadables.h -> builtins.h -> general.h -> <limits.h>

... resulting in a compile failure.

Below is a suggested fix.  While there, remove an unused variable.

Please Reply-To-All.

Thanks.

Marc.
