Is there something wrong with
AM_INIT_AUTOMAKE([-Wall -Werror])
As of Automake 1.10, -Wall includes -Wportability. So use
-Wall -Wno-portability -Werror
instead. Quoting from NEWS:

Thank you. But what exactly is
-Wno-portability
allowing?
---BEGIN quote from
http://sources.redhat.com/automake/automake.html#Invoking-Automake
-W CATEGORY
--warnings=category
Output warnings falling in category. category can be one of:
...
portability
portability issues (e.g., use of make features that are
known to be not portable)
---END quote
It is not so clear what this relates to. Is it only related to the
'make' program or also some portability issues outside of it? In other
words, can I simply say "no-portability" and don't relax strictness in
places not related to GNU make features?
The "e.g." in the above documentation bothers me. What else would
automake *not* complain about if I use "no-portability"?
