I applied this fix to my working crate out of .cargo. above are the errors when I try to just build the crate locally; so I can't test further. Let me know if you know what to do to get cargo build to work on latest. This patch maybe helpful to others.

20000 worked for me. I swear but when I tried using my patched crate from my application I found that cl kicked out the parameter as invalid. I need more than 2000. It was accepting of this large value at one point. I'm not sure what else to do.

if you look in the PR I added some code to use the env nasm on the machine if the developer hasn't pulled your specific windows tools.

my patched ring cargo builds just fine. when consuming it via local or git reference; I get fatal error C1056: cannot update the time date stamp field even with the /Zm2000
