Fairly sure we are using the mingw32 one. We put a #warning statement in
the .h file we expect to be using, and it is the one we get. And we only
have one libjpeg-8.dll in the build and runtime systems: the one from
OBS. If we hide that one, the runtime app complains it cannot find the
lib. So we are fairly certain it is the OBS one that is used.

The problem is that the structure we use is smaller than the one that
the library expects. Just to be sure no one left a messy pack directive
around, we even tried

#pragma pack(4) 

before including the jpeg include file. It made no difference.

That is pretty much getting to the end of my bag-o-tricks when trying to
solve issues on Windows platforms. That is why I wanted to try
rebuilding the mingw32-jpeg RPMS. But as I wrote, OBS was not happy.
