I know goluago does not advertise ARM support yet, but how much work would it be to add it?

Currently, compiling a go program that imports goluago on ARM gives the following output:

# command-line-arguments

Additional tests for checking Lua implementations for correctness are available at lua-TestMore website -- see section "The Lua Test Suite". Shall use them too, in addition to the testsuite provided by Lua authors I already use.

Given that non-cgo C won't be supported in Go 1.4+ anymore, a switch to rsc's c2go C->Go translator is a must. The good part is that I wanted for something like this to happen anyway, before even c2go was first announced. Also, advantages abound. The bad part is that it will probably require much work again.

void
·lua_tonumber(uintptr L, uintptr index, uintptr pret) {
    *((lua_Number*)pret) = lua_tonumber((lua_State*)L, (int)index);
}

How these can be compiled ?
