Thank you for the report and the patch.
However, there are plenty of systems for which base64 --decode would
not work either, so I've done this, which should work on a superset:
tests: avoid unnecessary "skip" without base64 -d support
* tests/pcre-jitstack: Try harder to find a base64 decoder:
Try 'base64 -d', 'base64 -D', 'openssl base64 -d' and perl's
MIME::Base64 decode_base64. The old code would skip at least on
OS X, for which base64 expects -D or --decode.
