I've got bison 2.3 on my Mac laptop, and it does what I expect (ie, it emits "typedef union YYSTYPE ..."). So do the oldest and newest bison versions I have handy (1.875 and 2.4.3), and both of their manuals specify that this is the expected behavior -- see http://www.gnu.org/s/bison/manual/html_node/Union-Decl.html about halfway down the page. A little bit of googling suggests that this is a bug or incompatibility with openbsd's m4 (a tool that bison relies on): http://comments.gmane.org/gmane.comp.parsers.bison.bugs/2708 That thread petered out without any clear resolution, but maybe you should check for m4 updates, or try installing GNU m4. regards, tom lane -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
