If Stephen's building native compilation under cygwin, perhaps he's
referring to an error message about not being able to load the ELN
file, either in the form of a "fork" failure, or an explicit complaint
about the dll base address conflicting with another dll that's already
been loaded.  For a 64-bit build, a restart of emacs seems to be
enough to cure the issue, although I have also had issues that didn't
seem to be resolved without doing a "rebase all".
I don't know if this behavior is considered a bug (in either libgccjit
or emacs) or just a basic limitation of using the cygwin platform.
It is definitely an annoyance when either installing packages or when
one of the package's features/modules is autoloaded the first time.
