[OpenSmalltalk/opensmalltalk-vm] jpeg plugin crashes in win64 cygwin/mingw builds (#526)

David T Lewis
 

Easy to reproduce: JPEGReadWriter2Test suite run with a VM compiled with cygwin (mingw cross platform) toolchain.
This might be related to this commit or not:
7e0018d

The commit tells that assert VM crashes even when built with MSVC toolchain (w or w/o clang-cl.exe).

I think that a good part of the problem is that we call _setjmp but then longjmp instead of _longjmp in error_exit.

If we (re)#define setjmp then we must also (re)#define longjmp _longjmp
