There may be a bug in the msvc detection part of rustc

[FirTech]

I created a new project using cargo, and then created a build.rs file with only an empty main function.
Then I execute \VC\Auxiliary\Build\vcvarsall.bat x86 and then execute cargo build --release --target=i686-pc-windows-msvc and it will report an error: "The library computer type "x86" conflicts with the target computer type "x64" "
I think there may be a bug in the msvc detection part of Rustc.

Thanks for the report! Could you try with the nightly compiler in case this is fixed in the next version? If you're using rustup you can use nightly like this:

rustup install nightly
cargo +nightly build --release --target=i686-pc-windows-msvc

ok, I tried the nightly version, it can be built normally, and I look forward to stabilizing this function as soon as possible

This is fixed by #85649 and the next stable version (1.54) should have that fix. Thanks!
