Unable to get oxipng or OptiVorbis to compile with VC8 libs with static crt

[the-r3dacted]

I've been playing around with the cargo config.toml, setting vc8 libs, enabling libucrt, commenting and uncommenting various items, but I'm just unable to get them to compile. I always get get undefined symbol errors with VC8 while both compile fine with VS2017 + static.

For oxipng I get this:

error: could not compile `oxipng` (bin "oxipng") due to 1 previous error

For OptiVorbis, I also get duplicate symbol errors doing this, but I manually edited the llvm linker to just warn for them. Afterwards I get an error.

C:\Projects\OptiVorbis>cargo build --release --target i686-rust9x-windows-msvc

This may become a hard error in the future; see <https://github.com/rust-lang/cargo/issues/6313>.

error: could not compile `optivorbis` (lib) due to 1 previous error

Any idea what this could be?

[seritools]

Yeah the C99 math stuff is always tricky.

Please post your .cargo/config.tomls for the respective errors, and the full linker command line.
