- use proper Win64 gcc calling convention when calling initcgo on amd64 - increase g0 stack size to 64K on amd64 to make it the same as 386 - implement C.sleep - do not use C.stat, since it is renamed to C._stat by mingw - use fopen to implement TestErrno, since C.strtol always succeeds on windows - skip TestSetEnv on windows, because os.Setenv sets windows process environment, while C.getenv inspects internal C runtime variable instead R=golang-dev, vcc.163, rsc CC=golang-dev https://golang.org/cl/5500094
