It looks like 3 different issues.

This looks like our bug that surfaces under MinGW. In the past the
signed type was changed to an unsigned type, which squashed most
problems. I guess we need to do a little more.

Hmm... Weird.
I'm not sure what to do with this one. It looks like MinGW is
providing malformed commands.
Has anyone come across it before?

Ugh... That looks like a mashup of Intel ICC compiler warning
suppression (-wd186) and Sun CC pic option (-KPIC).
I think we are misidentifying the compiler. Could you provide the output of:
g++.exe -dumpmachine
And:
g++.exe --version
