Hi Manuel,

I don't know what "explicit module maps" means.

The bug report links to a mailing list thread. Does that provide more
context? IOW: Why make

 /usr/include/module.modulemap

contended by everything that installs into /usr ? Was a solution of
uncontended

 /usr/include/<name>.modulemap

considered and discarded? Why?

Thanks,

Steve.
