Autoconf generates additional code for the first AC_CHECK_HEADERS call in the script. If the first call is within an if-block, the additional code is put inside the if-block too, even though it is needed by subsequent AC_CHECK_HEADERS checks and should always be executed. When I moved the pthread-related checks earlier in the script, the pthread.h test inside the block became the very first AC_CHECK_HEADERS call in the script, triggering that problem. To fix, use AS_IF instead of plain shell if. AS_IF knows about that issue, and makes sure the additional code is always executed. To be completely safe from this issue (and others), we should always be using AS_IF instead of plain if, but that seems like excessive caution given that this is the first time we have trouble like this. Plain if-then is more readable than AS_IF. This should fix compilation with --disable-thread-safety, and hopefully the buildfarm failure on forgmouth, related to mingw standard headers, too. I backpatched the previous fixes to 9.5, but it's starting to look like these changes are too fiddly to backpatch, so commit this to master only, and revert all the pthread-related configure changes in 9.5. |

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.
