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.
