    This occurs when one of the libraries compiled using the not SJLJ
    build of MinGW. (dwarf, for example)

I fixed it, eventually, after much messing around with PATH. The 
strawberry perl c compiler, an irrelevant sjlj build, had snuck in 
somewhere along the line and had been picked up by bjam.

As it turns out, I had to download TDM-GCC-4.7.1, mingw & sjlj to build 
against Qt5.

Boost, and my engine's code were happy to use Mingw 4.6.2, dwarf build, 
but once the libraries had compiled alright, complained badly during my 
code's compilation when I tried gcc 4.7.1.

Spent the rest of the day fixing up windows IO and all those enchanting 
little differences between OS designs :P

I now have at least four MinGW toolchains but I'm not looking for trouble.
