[PATCH v2] libs/store: make build without PTHREAD_STACK_MIN
Posted by Manuel Bouyer 3 years, 2 months ago 
On NetBSD, PTHREAD_STACK_MIN is not available.
If PTHREAD_STACK_MIN is not defined, define it to 0 so that we fallback to
DEFAULT_THREAD_STACKSIZE

There was also a suggestion to use MAX(PTHREAD_STACK_MIN,
DEFAULT_THREAD_STACKSIZE). Is maybe MAX not defied here?

Thanks, Roger.

TBH, I was planning to submit an incremental cleanup doing this
separately.  It would be cleaner than putting cleanup into the "fix
NetBSD" patch.
