Arch Linux

Summary and Info:
community/mingw-w64-gcc is compiled without --disable-libssp, which for some odd reason forces you to link against `-lssp`.

This breaks cross-compiling Go code using cgo.

Steps to Reproduce:

hg clone -u release https://code.google.com/p/go
cd go
env GOOS=windows GOARCH=amd64 CGO_ENABLED=1 CC_FOR_TARGET="x86_64-w64-mingw32-gcc" ./make.bash

Errors out with:


# runtime/cgo

Adding -fno-stack-protector and -D_FORTIFY_SOURCE=0 doesn't do anything, the only way to successfully compile it is to link against ssp

env GOOS=windows GOARCH=amd64 CGO_ENABLED=1 CC_FOR_TARGET="x86_64-w64-mingw32-gcc -fno-stack-protector -D_FORTIFY_SOURCE=0 -lssp" ./make.bash
