Right, knowing it was on master and not stable helped a lot. This seems 
to have resolved the issue - many thanks.
However I can't compile with openmp, even after building libgomp. The 
file clearly exists in
$(MXE_DIR)/usr/lib/gcc/x86_64-w64-mingw32.shared/4.8.2/libgomp.spec
- though this is a very odd place for it to sit, given it matches 
neither the x86_64-w64-mingw32-gfortran version (4.6.3) nor the host 
gfortran version (4.8.1)

I used the OpenBLAS build but had to modify the build instructions 
slightly as I need AVX support (TARGET=SANDYBRIDGE) - I suspect the 
optimal build is actually to use its dynamic arch support and build 
versions for i686/SSE4/AVX

Many thanks,

Jonathan.
