 In Code::Blocks all the projects are automatically built in a correct order (DLL's then apps) by doing 'build->build workspace'.
 In VC6, you'll have to build the projects one by one.
 
-The needed regexp library TRE can be found here http://laurikari.net/tre/. Unzip and place the "tre-0.8.0" folder into the "windows" folder.

+Jack requires a regexp library. TRE is the recommended choice - source available here http://laurikari.net/tre/. 
+The TRE build is not fully integrated in the Code::Blocks environment and it is therefore recommended that TRE is installed separately at the OS level.

+Using the waf build tools in conjunction with MSVC, jack will build with recent compilers, known good up to 2017 15.9, including #define logic consuming the _MSC_VER macro to support build with older versions. The Visual Studio workspace was last tested at VC6.
 
-The Visual Studio workspace is limited to VC6. JACK will not compile on most recent MSVC's. The fact is recent compilers (MSVC7, 8 or 9) don't agree with some of the JACK sources.
-But now you can compile JACK using GCC, with MingW. The project is actually organized in a Code::Blocks workspace. This is a simple and efficient way to compile the whole project.
+You can compile JACK using GCC, with MingW. The project is organized in a Code::Blocks workspace to support this, but see the warning at the start of this README. 
 
-But for some reasons, you need to compile JACK using a SJLJ version of G++ (available on MingW website).
-Current GCC/G++ version (3.4.5) doesn't includes SJLJ so you'll have to use another one.
-JACK needs the use of SJLJ exceptions instead of DW2 because exceptions are exchanged between DLL's, and DW2 does not allow to throw an exception out of a DLL, so it wouldn't be cought.
