IIUC The observed problem is some lack of parallelism when running 'make
-jX'. It is likely that Make derives the dependency graph between
targets solely from their prerequisites. So any lack of parallelism
seems related to some unnecessary prerequisites added in the provided
I am closing this bug since this seems like a bug in the Makefile you
have written not in Automake. Feel free to reopen it if you can provide
a minimal example demonstrating that the Make rules generated by
Automake could have more parallelism.
