3.1.16

  This is mostly a bug fix release.

  - Work around some Windows CMD.EXE programs that will fail executing a totally empty batch file. -- Rene R.
  - Add support for detection and building with `vc9`. -- John P.
  - Plug memory leak when closing out actions. Thanks to Martin Kortmann for finding this. -- Rene R.
  - Various improvements to `__TIMING_RULE__` and `__ACTION_RULE__` target variable hooks. -- Rene R.
  - Change `JAMDATE` to use common ISO date format. -- Rene R.
  - Add test for result status values of simple actions, i.e. empty actions. -- Rene R.
  - Fix buffer overrun bug in expanding `@()` subexpressions. -- Rene R.
  - Check empty string invariants, instead of assuming all strings are allocated. And reset strings when they are freed. -- Rene R.
  - Add `OSPLAT=PARISC` for HP-UX PA-RISC. -- Boris G.
  - Make quietly actions really quiet by not printing the command output. The output for the quietly actions is still available through `__ACTION_RULE__`. -- Rene R.
  - Switch intel-win32 to use static multi thread runtime since the single thread static runtime is no longer available. -- Rene R.
  - When setting `OSPLAT`, check `__ia64` macro. -- Boris G.
  - Get the unix timing working correctly. -- Noel B.
  - Add `-fno-strict-aliasing` to compilation with gcc. Which works around GCC-4.2 crash problems. -- Boris G.
  - Increased support for Python integration. -- Vladimir P., Daniel W.
  - Allow specifying options with quotes, i.e. `--with-python=xyz`, to work around the CMD shell using `=` as an argument separator. -- Rene R.
  - Add values of variables specified with -s to .EVNRION module, so that we can override environment on command line. -- Vladimir P.
  - Make NORMALIZE_PATH convert \ to /. -- Vladimir P.

3.1.15

  This release sees a variety of fixes for long standing Perforce/Jam problems. Most of them relating to running actions in parallel with the -jN option. The end result of the changes is that running parallel actions is now reliably possible in Unix and Windows environments. Many thanks to Noel for joining the effort, to implement and fix the Unix side of stuff.

  - Add support for building bjam with pgi and pathscale toolsets. -- Noel B.
  - Implement running action commands through pipes (-p option) to fix jumbled output when using parallel execution with -j option. This is implemented for Unix variants, and Windows (Win32/NT). -- Rene R., Noel B.
  - Add "sun" as alias to Sun Workshop compiler tools. -- Rene R.
  - Set MAXLINE in jam.h to 23k bytes for AIX. The piecemeal archive action was broken with the default MAXLINE of 102400. Because the AIX shell uses some of the 24k default buffer size for its own use, I reduced it to 23k. -- Noel B.
  - Make use of output dir options of msvc to not polute src dir with compiled files. -- Rene R.
  - A small fix, so -d+2 will always show the "real" commands being executed instead of casually the name of a temporary batch file. -- Roland S.
  - Add test to check 'bjam -n'. -- Rene R.
  - Add test to check 'bjam -d2'. -- Rene R.
  - Bring back missing output of -n option. The -o option continues to be broken as it has been for a long time now because of the @ file feature. -- Rene R.
  - Update GC support to work with Boehm GC 7.0. -- Rene R.
  - Revert the BOOST_BUILD_PATH change, since the directory passed to boost-build should be first in searched paths, else project local build system will not be picked correctly. The order had been changed to allow searching of alternate user-config.jam files from boost build. This better should be done with --user-config= switch or similar. -- Roland S.
  - Initial support for defining action body from Python. -- Vladimir P.
  - Implement @() expansion during parse phase. -- Rene R.
  - Define OSPLAT var unconditionally, and more generically, when possible. -- Rene R.
  - Fix undeclared INT_MAX on some platforms, i.e. Linux. -- Rene R.
  - Modified execunix.c to add support for terminating processes that consume too much cpu or that hang and fail to consume cpu at all. This in support of the bjam -lx option. -- Noel B.
  - Add internal dependencies for multi-file generating actions to indicate that the targets all only appear when the first target appears. This fixes the long standing problem Perforce/Jam has with multi-file actions and parallel execution (-jN). -- Rene R.
  - Add test of -l limit option now that it's implemented on windows and unix. -- Rene R.
  - Add test for no-op @() expansion. -- Rene R.
  - Handle invalid formats of @() as doing a straight substitution instead of erroring out. -- Rene R.
  - Various fixes to compile on SGI/Irix. -- Noel B.
  - Add output for when actions timeout with -lN option. -- Rene R., Noel B.
  - Add needed include (according to XOPEN) for definition of WIFEXITED and WEXITSTATUS. -- Markus S.
