| // Unix. This crate also, however, provides "import libraries" for the |
| // MinGW targets. There's an import library per dll in the windows |
| // distribution which is what's linked to. These custom import libraries |
| // are used because the winapi crate can reference Windows functions not |
| // present in the MinGW import libraries. |
| // |
| // For example MinGW may ship libdbghelp.a, but it may not have |
| // references to all the functions in the dbghelp dll. Instead the |
| // custom import library for dbghelp in the winapi crates has all this |
| // information. |
| // |
| // Unfortunately for us though the import libraries are linked by |
| // default via `-ldylib=winapi_foo`. That is, they're linked with the |
| // `dylib` type with a `winapi_` prefix (so the winapi ones don't |
| // conflict with the system MinGW ones). This consequently means that |
| // the binaries we ship of things like rustc_trans (aka the rustc_trans |
| // DLL) when linked against *again*, for example with procedural macros |
| // or plugins, will trigger the propagation logic of `-ldylib`, passing |
| // `-lwinapi_foo` to the linker again. This isn't actually available in |
| // our distribution, however, so the link fails. |
| // |
| // To solve this problem we tell winapi to not use its bundled import |
| // libraries. This means that it will link to the system MinGW import |
| // libraries by default, and the `-ldylib=foo` directives will still get |
| // passed to the final linker, but they'll look like `-lfoo` which can |
| // be resolved because MinGW has the import library. The downside is we |
