Early Roguelike Collection: srogue/weapons.c annotate

annotate srogue/weapons.c @ 239:837044d2c362

Merge the GCC5 and build fix branches. This fixes all warnings produced by GCC 5, except the ones related to system functions. Those could be fixed by including the proper headers, but it would be better to replace the system-dependent code with functions from mdport.c.
