Ick.  That is of course why it worked for me when I tested it :-(

This is probably what we'd better do.  Otherwise we have
build-context-dependency in the system's behavior, which is bad.

Peter, any thoughts on this one way or the other?  At the moment
plpgsql's scan.l seems to be the only use of '%option case-insensitive'
but we have enough flex lexers laying about that I wouldn't be surprised
to have this same risk elsewhere.  Is it reasonable to try to force
LANG=C in some global fashion during the build?
