[M3devel] need some help with linker error

[Jay K]

This is fixed now too.
Dragisha had introduced heap corruption in FSWin32.m3 trying to improve Unicode support.

Hm. That leaves me with:

I updated m3-sys/mklib to ignore these.
Let me know if there are any more problems.
 
Thanks,

No. There is no chance of this.

No. There is no chance of this either.
 
 
I forget how we generate the .def file but we need to exclude names "like" this -- that start _xmm at .
These are floating point constants for code that uses sse2.
You are targeting 32bit, right?
Still, I guess these might occur, with newer compilers.
I'll look into it.
We already have to code exclude the older forms of floating point constants.
