Hi Paul,
A friend of mine pointed out the problem above. I have no idea what
POSIX says about this syntax for defining rule:
a: b c = { action };
instead of the classic
a: b c { action };
I'm not fond of supporting additional syntaxes, but if this is
mandated by POSIX, it seems that we have 1.875 :)
PS/ Byacc accepts this grammar
PS2/ This reminds me of %<, %=, %> and other historical attrocious
synonyms for %left, %nonassoc etc. Does POSIX say something about
them?
PS3/ Thomas, in any case, I would renovate my grammar as suggested
instead of moving away from Bison.
