specparse.y and specscanner.l used "string" as a token name. Now, bison likes to define each token name as a macro for the token code it assigns, which means those names are basically off-limits for any other use within the grammar file or included headers. So names as generic as "string" are dangerous. This is what was causing the recent failures on protosciurus: some versions of Solaris' sys/kstat.h use "string" as a field name. With late-model bison we don't see this problem because the token macros aren't defined till later (that is why castoroides didn't show the problem even though it's on the same machine). But protosciurus uses bison 1.875 which defines the token macros up front. This land mine has been there from day one; we'd have found it sooner except that protosciurus wasn't trying to run the isolation tests till recently. To fix, rename the token to "string_literal" which is hopefully less likely to collide with names used by system headers. Back-patch to all branches containing the isolation tests.
PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: http://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at http://www.postgresql.org/download/. For more information look at our web site located at http://www.postgresql.org/.
