Re: [MPS test] `void-function igc--collect` on scratch/igc branch (commit: `42731228d2`)

[Eval Exec <execvy@gmail.com>]

The first time I built the scratch/igc branch, I didn't have the mps
package installed locally. That's why I encountered the void-function
igc--collect error. After installing mps and rebuilding the
scratch/igc branch, the igc--collect function became available, and
(featurep 'mps) returned t.
