[Message part 2 (message/rfc822, inline)]
Hi - you have each reported Automake test failures on Solaris.
I've just pushed a fix from Bogdan (thanks Bogdan!) for some of these,
which (sometimes with other fixes already made) closes some bugs.
Bogdan explains the details of the latest:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=45205#13
Other problems remain and still need debugging, as Bogdan explains in:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=45205#16
If anyone has time and interest to try bootstrapping current automake,
run the test suite, and find what still fails and why, that would be
great. --thanks, karl.
