Thanks for noticing this. In fact, I think it can be fixed more easily
(though I'm busy on a related issue first). The way the compile
workspace is used in PCRE2 has changed since PCRE1, and making its size
depend on LINK_SIZE is no longer relevant. Removing this dependency
should fix the issue. I'll investigate in due course.
