Either configure picks up the wrong assembler routines, or the
routines are not designed to work with windows calling convention.
I agree with this analysis. Probably one the the files in
mpn/x86_64/coreisbr claims to work for "DOS64" but actually doesn't.
Could you please try the following for us:
0. Grab a snapshot, to put us on the same source code.
1. Hide all ".asm" files from mpn/x86_64/coreisbr in, say,
2. Repeat your configure+build procedure. I assume things will now work.
3. Replace file after file from mpn/x86_64/hidden to mpn/x86_64/coreisbr,
