-c-stack: stop using SIGSTKSZ
-
-It’s been proposed to stop making SIGSTKSZ an integer constant:
-https://sourceware.org/pipermail/libc-alpha/2020-September/118028.html
-Also, using SIGSTKSZ in #if did not conform to current POSIX.
-Also, avoiding SIGSTKSZ makes the code simpler and easier to grok.
-* lib/c-stack.c (SIGSTKSZ): Remove.
-(alternate_signal_stack): Now a 64 KiB array, for simplicity.
-All uses changed.
-
