MinGW. GCC on W98?

Does anyone know of a Win32 binary that does work on W98? I found a late 7Z
package that claimed x86 support intended for Win32, but it would not run in
'DOS mode'. Meaning it couldn't even tell I was in a Windows session!

I have the Dev-CPP-supplied MinGW but it's older, and I need to try a newer
one because I'm exploring a file dialog API call. Code that compiles and runs
fine using TCC crashes COMDLG32.DLL when compiled by GCC v3.4.5, even though
it compiles with no errors or warnings.

There's only one thing to try, that's a newer version, because this really
DOES look like a bug, and not in my code for once. But right now I can't find
a simple download of a MinGW binary that I can be sure will run on W9X. I
could download several tens, maybe hundreds of megabytes, from all and sundry
out there and draw blank after blank, so I could really use some help finding
one that works.

I may be able to find one inside other tools, like 'DialogBlocks' or
whatever, but this is like shooting blind, hoping to hit something, anything
at ALL. If you know somethign better than this, please post. I'd use the one
from Dev-cpp if they updated it, but I don't think they ever do now.
