GCC required?

[oconnor0]

While attempting to build ripgrep which depends on kernel32-sys, I get the following build failure. Is kernel32-sys supposed to depend upon gcc for linking?

error: could not exec the linker gcc: The system cannot find the file specified. (os error 2)

[retep998]

Rust has to link binaries (in this case the build script for kernel32-sys) using a linker and because you're using i686-pc-windows-gnu the linker Rust uses is gcc. This failure is not winapi's fault however, but a recent regression in Rust itself.

Fixed upstream.
