There's a bunch of places where we do that. Why are just those two triggering a warning?

I only hit two in my build and didn't think to check the rest. I'll fix those up later. |
Talk about silly warning... |

GCC 14 introduces a new -Walloc-size included in -Wextra which gives: ``` src/tool_operate.c: In function ‘add_per_transfer’: src/tool_operate.c:213:5: warning: allocation of insufficient size ‘1’ for type ‘struct per_transfer’ with size ‘480’ [-Walloc-size] 213 | p = calloc(sizeof(struct per_transfer), 1); | ^ src/var.c: In function ‘addvariable’: src/var.c:361:5: warning: allocation of insufficient size ‘1’ for type ‘struct var’ with size ‘32’ [-Walloc-size] 361 | p = calloc(sizeof(struct var), 1); | ^ ``` The calloc prototype is: ``` void *calloc(size_t nmemb, size_t size); ``` So, just swap the number of members and size arguments to match the prototype, as we're initialising 1 struct of size `sizeof(struct ...)`. GCC then sees we're not doing anything wrong.
