FLEX listens to M4 envvar, unset.
Does it help to set M4=/opt/freeware/bin/m4 in the environment, so configure is
forced to take GNU m4?
Once upon a time, I've had similar problems here, although with older gcc, and
use attached patch to fix it - maybe it is of some help here as well.
Problem is that flex does listen to the M4 environment variable. Dependent on
PATH, configure may find AIX m4 (/usr/bin) or GNU m4 (/opt/freeware/bin).
When M4=AIX-m4, flex-generated code breaks.
