The mingw-w64 compiler can compile for both x86 and x64 windows. I actually use
the x86 target, and had to apply the patch to successfully build 32-bit mono.
So I think it is actually correct that this affects the i386 build.

As I wrote, I just copied this patch from the upstream libgc project.
Unfortunately the cvs of libgc
(http://bdwgc.cvs.sourceforge.net/viewvc/bdwgc/bdwgc/) is currently unavailable
due to the recent Sourceforge attack, so I cannot look up their cvs commit.

I do not know much about embedding Mono, but shouldn't they only rely on
symbols that are defined in publicly exposed header files?
