Hi,

It seems that the DOT_I_FILES in libguile/Makefile.am are missing
explicit dependency information and thus are prone to race conditions
during parallel builds.

See build log at:

https://headcounter.org/hydra/build/581960/nixlog/11/raw

And discussion here:

How would this work?  The .deps includes a dependency e.g. of
libguile_2.0_la-instructions.lo on vm-i-system.i.  That should be
sufficient, no?  Is it not guaranteed that .deps are there or something?

I have no idea, because I have reported that bug in 2014 and things
might have changed in-between in addition to me forgetting about the
specifics of this bug.

So I guess this bug can be closed and I'll reopen a new bug if it
happens again.

Yeah, our bad for not striking while the iron was hot.  Let's pick this
up again when/if we can reproduce it :)

Cheers,
