cargo:warning=cl : Command line error D8021 : invalid numeric argument '/Wno-unused-parameter'

I have an error on win10:
running: "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\amd64\cl.exe" "/nologo" "/MD" "/Z7" "/I" "odpi/include" "/I
" "odpi/src" "/W4" "-Wno-unused-parameter" "/FoC:\Rust\rms\target\debug\build\oracle-a41627ac717eac75\out\odpi/src\dpiConn.o"
"/c" "odpi/src/dpiConn.c"
cargo:warning=cl : Command line error D8021 : invalid numeric argument '/Wno-unused-parameter'
exit code: 2

To fix this error I removed line .flag("-Wno-unused-parameter") from build.rs. And now it works for me.

Thank you!
The -Wno-unused-parameter is an option for gcc compiler. It should be set only for gcc.

@vlad-korotych Thaks. I apply -Wno-unused-parameter only when it is supported by using flag_if_supported.
