MarsSeed [1] filed a deletion request for lib32-libmpc [2]: I suggest this outdated lib32 package can be deleted. This is a low-level library used for numerical functions and scientific/mathematical computations. Arch [core] carries the 64-bit build. Package last updated in 2019, whereas there was a newer release of this in 2020. But no one requested an update. There are also no user comments or votes. It has no dependents on AUR. Safe to delete.
