maybe he is reluctant to add it since it would not be a constant
from the Lua side ?
just add and export a C function along this lines to your package:
static int get_bufsiz ( lua_State * const L )
{
lua_pushinteger ( L,
// without checking the macro's value :-/
#if defined (BUFSIZ)
BUFSIZ
#else
0 // maybe no good idea ?
#endif
) ;
return 1 ;
}
