bitflags compilation errors

[joIivier]

Hello,
when I add openssl as a dependent crate to my crate, I get a lot of compilations errors within openssl like:

error[E0412]: cannot find type `Pkcs7Flags` in this scope
   --> /home/jolivier/.cargo/registry/src/index.crates.io-6f17d22bba15001f/openssl-0.10.50/src/pkcs7.rs:262:16
    |

    |                ^^^^^^^^^^ not found in this scope

error[E0422]: cannot find struct, variant or union type `X509VerifyFlags` in this scope
   --> /home/jolivier/.cargo/registry/src/index.crates.io-6f17d22bba15001f/openssl-0.10.50/src/x509/verify.rs:116:9

    |           ^^^^^^^^^^^^^^^ help: a struct with a similar name exists: `X509VerifyParam`

Or

error[E0412]: cannot find type `SslVerifyMode` in this scope
    --> /home/jolivier/.cargo/registry/src/index.crates.io-6f17d22bba15001f/openssl-0.10.50/src/ssl/mod.rs:2339:52

I have 60 errors in total so not reproducing all of them here. They seem to be all related to the use of the bitflags! macro. All of the errors I checked were related to a struct declared via this macro.
I tried in stable and nightly versions:

cargo -V
cargo 1.70.0-nightly (0e474cfd7 2023-03-31)
cargo +stable -V
cargo 1.68.2 (6feb7c9cf 2023-03-26)

My Cargo.toml:

[package]
name = "xxx"
version = "0.1.0"
authors = ["xxx"]
edition = "2021"

[dependencies]
ansi_term = "*"
env_logger = "*"
log= { version = "0.4", features = ["max_level_debug", "release_max_level_warn"] }
maplit = "1.0"
openssl = "0.10"
rand = "0.8"
rand_distr = "0.4"
spade = "2.1"
tempfile = "3"
time = "0.3"

I tried the vendored build but got the same issue.

Your local copy of bitflags may be corrupted. Try deleting your local cargo cache and rebuilding.

Ok, I dig deeper and found the issue:
bitflags 1.0.3 does not support Edition 2018 and this is fixed via bitflags/bitflags#165
I don't understand why version 1.0.3 was chosen but after deleting my local cargo cache it uses version 1.3.2 that doesn't have this issue anymore.
Thanks for the help anyway.
