# If we're compiling for MSVC then we, like most other distribution builders,
|
|
|

# switch to clang as the compiler. This'll allow us eventually to enable LTO
|
|

|
# amongst LLVM and rustc. Note that we only do this on MSVC as I don't think
|

|
|
# clang has an output mode compatible with MinGW that we need. If it does we
