changes in sbcl-1.4.14 relative to sbcl-1.4.13:
* enhancement: attempting to build on openbsd 6.0 or newer without the wxallowed mount option now results in a more useful error message. * enhancement: by popular demand, SB-EXT now exports two functions HEAP-ALLOCATED-P and STACK-ALLOCATED-P to assist in writing debug assertions that objects in hash-tables are not stack-allocated, etc. * bug fix: restored sb-thread support on OpenBSD.
