[pcre-dev] pcretest in 8.20

Hi, and Thank You for your great work on the PCRE package!

A minor issue is that pcretest.c does not build without SUPPORT_JIT having been defined.
It gets unresolved externals in linkage for the new JIT methods that were not included when
the base library was built.

Pcretest.c has one #ifdef condition for indicating SUPPORT_JIT but more may be needed.
Perhaps something like this DIFF would suffice:
============================
588a589
> #ifdef SUPPORT_JIT
592a594
> #endif
2503a2506
> #ifdef SUPPORT_JIT
2511a2515
> #endif
3093a3098
> #ifdef SUPPORT_JIT
3094a3100
> #endif
============================

Thanks and Best Regards,

Guy.
