* jit: allow building with ancient MSVC versions
Visual Studio older than 2013, fails to build with JIT enabled,
because it is unable to parse non C89 compatible syntax, with
mixed declarations and code.
While most recent compilers wouldn't even report this as a warning
since it is valid C99, it could be also made visible by adding to
gcc/clang the -Wdeclaration-after-statement flag at build time.
Move the code below the affected definitions.
* pcre2grep: avoid mixing declarations with code

PCRE2 - Perl-Compatible Regular Expressions
The PCRE2 library is a set of C functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5. PCRE2 has its own native API, as well as a set of wrapper functions that correspond to the POSIX regular expression API. The PCRE2 library is free, even for building proprietary software. It comes in three forms, for processing 8-bit, 16-bit, or 32-bit code units, in either literal or UTF encoding.
PCRE2 was first released in 2015 to replace the API in the original PCRE library, which is now obsolete and no longer maintained. As well as a more flexible API, the code of PCRE2 has been much improved since the fork.
Download
As well as downloading from the GitHub site, you can download PCRE2 or the older, unmaintained PCRE1 library from an unofficial mirror at SourceForge.
You can check out the PCRE2 source code via Git or Subversion:
git clone https://github.com/PhilipHazel/pcre2.git
svn co https://github.com/PhilipHazel/pcre2.git
Contributed Ports
If you just need the command-line PCRE2 tools on Windows, precompiled binary versions are available at this Rexegg page.
A PCRE2 port for z/OS, a mainframe operating system which uses EBCDIC as its default character encoding, can be found at http://www.cbttape.org (File 939).
Documentation
You can read the PCRE2 documentation here.
Comparisons to Perl's regular expression semantics can be found in the community authored Wikipedia entry for PCRE.
There is a curated summary of changes for each PCRE release, copies of documentation from older releases, and other useful information from the third party authored RexEgg PCRE Documentation and Change Log page.
Contact
To report a problem with the PCRE2 library, or to make a feature request, please use the PCRE2 GitHub issues tracker. There is a mailing list for discussion of PCRE2 issues and development at pcre2-dev@googlegroups.com, which is where any announcements will be made. You can browse the list archives.
