[bug-mailutils] Compiler warnings

[Ken Brown]

I'm getting the following compiler warnings on Cygwin with gcc-5.4.0:

system.c:122:30: warning: unused variable ‘auth_data’ [-Wunused-variable]
   const struct mu_auth_data *auth_data = key;

copyfile.c:166:16: warning: cast from pointer to integer of different 
size [-Wpointer-to-int-cast]
    if (fchmod ((int) trans[0], mode))
                ^
copyfile.c:196:17: warning: cast from pointer to integer of different 
size [-Wpointer-to-int-cast]
     if (fchown ((int) trans[0], uid, gid))
                 ^

The attached patch silences the warnings.  I'm not sure whether the 
patch to copyfile.c is correct; it seems strange to be casting a pointer 
to an integer which is then used as a file descriptor.  But I admit that 
I haven't studied the code.
