Windows (32-bit) building PCRE as a DLL.
We have defined a few non-default values in config.h.

PCRE version 8.20 2011-10-21
Compiled with
UTF-8 support
No Unicode properties support
No just-in-time compiler support
Newline sequence is LF
\R matches all Unicode newlines
Internal link size = 2
POSIX malloc threshold = 10
Default match limit = 50000
Default recursion depth limit = 2500
Match recursion uses stack

That's where I broke it, thank you. I did not understand that dummy
functions would be provided when SUPPORT_JIT was not defined.
I'm not (yet) using the new JIT functionality so I did not include
pcre_jit_compile.c in the build at all. Thus my unresolved externals.

Adding compilation of pcre_jit_compile.c (as I have since seen stated
in the documentation) does yield a successful build with no alteration
of pcretest.c.

Ah, it turns out that I am the "odd interaction that is causing this".

On the other hand it seems pcretest may currently be the only reason to
use pcre_jit_compile.c with the base library. I'm guessing that may not
hold true in future versions. It's great you've enabled such a large
feature without breaking the core functionality.

Thank you.
