Can you please be more specific on what is broken and needs to be fixed
here? Why should we avoid defining a macro within a function?

Sorry for that.
There is nothing broken, It is just about using a more common style.

First, define MIN() macro as defined in other files (wmm.c), and make
it available for all the file instead of #define it, and then #undef
it.

Second, add missing brackets around arguments.
