bug #22010: The increased stack rlimit is inherited by the subprocesses to make. |

* make.h: Move SET_STACK_SIZE determination to make.h. |
|
* main.c (main): New global variable, STACK_LIMIT, holds the |
|
original stack limit when make was started. |
|
* job.c (start_job_command): Reset the stack limit, if we changed it. |
|
Fixes Savannah bug #22010. |
