MinGW "The procedure entry point libiconv could not be located ..."

I've got a standard C library that compiles just fine on Mac OS X using gcc.

I've examined the C compilers available for Windows, and choose MinGW for a couple reasons:

• MS's tools don't support C99
• Cygwin et. al. adds an extra level of complexity with the posix emulation that I don't want
• Can't get lcc-win32 to work

But, when I try to build my library, I'm getting this:

This stuff all seems very archaic, and there are practically no decent resources online that I can find.

Any help would be greatly appreciated.

Thanks.

EDIT:

It doesn't matter what I'm trying to build. Even if I just make a single file with a function that adds two numbers. It crashes. Doesn't seem to have anything to do with the source code or the options passed to gcc at all. I think this is a problem with my MinGW setup and not with my project.
