The (Open_Source) IM gang only supports the msvc compiler on windoz and my research suggests that you have to use the same (32bit) compiler and the same (i386??) optimizations to link to their binary distributions.

But doesn't your Strawberry build link to their binary distributions ?
Mine used their dlls, though I (perhaps unnecessarily) rebuilt the import libs from those dlls using gendef and dlltool.

I get the same test failures as you ... though, occasionally, the montage tests succeed.

Do you know how siginificant those failures are ? (I don't.)
They're not *obviously* of far-reaching siginificance:

Even the slightest and most insignificant variation would result in a failed signature match.
And 1.00003051827663 is only just outside the "maximum-error".
