Ok, let me revise that from "gcj-mingw will never have stack traces"
to "gcj-mingw will have stack traces very soon" =)
Thanks for the code snippet, I haven't done x86 assembly in eight
years, and I wasn't looking forward to going back to it =)
I'll probably get around to putting this in sometime after 3.1 is
released.
Interestingly, why does gcj use DWARF2 info to generate stack traces
on Linux instead of just doing this?
