lrandom vs C++

["Alexander Gladysh" <agladysh@...>]

Hi, list!

The lrandom module as it is does not compiles as C++ code:

    lrandom.c: In function 'MT* Pget(lua_State*, int)':
    lrandom.c:25: error: invalid conversion from 'void*' to 'MT*'
    lrandom.c: In function 'MT* Pnew(lua_State*)':
    lrandom.c:30: error: invalid conversion from 'void*' to 'MT*'

Proposed patch below.

Alexander.
