Steven - is that a definitive instruction or give-this-a-try advice?

I have tried gcc but I am not sure it works. The math lib names end-up
decorated with "c99" - MinGW does not conform to c99. MinGW is not
actually gcc - it doesn't use glibc.

Actually, I am trying to build a library (libDAI) which uses Boost.
libDAI builds 'out-of-the-box' on Linux but with MinGW, the build fails
with an obscure problem. My first suspicion is an issue with my
MinGW-built Boost libs. (Could be an issue with libDAI/MinGW, I accept.
But I'd like to be clear that's my problem, not something with the Boost

I have also tried toolset=gcc-no-cygwin (which passes the -no-cygwin
flag to gcc thereby invoking the mingw interface). This seems to produce
warnings about c89 not supporting long doubles (which I'd expect with
MinGW) but the libDAI build still breaks.

Regardless, what has happened to the toolset=mingw option?
