33. Compile invalid UTF check in JIT test when only pcre32 is enabled.
34. For some time now, CMake has been warning about the setting of policy
CMP0026 to "OLD" in CmakeLists.txt, and hinting that the feature might be
removed in a future version. A request for CMake expertise on the list produced
no result, so I have now hacked CMakeLists.txt along the lines of some changes
I found on the Internet. The new code no longer needs the policy setting, and
it appears to work fine on Linux.
