gunmake/doc, branch 3.99.90

Update copyright for changes in 2013.

2013-05-17T05:47:42Z

Add requirement for plugin_is_GPL_compatible symbol in loaded objects.

2013-05-15T02:53:42Z

Add a new variable: GNUMAKEFLAGS

2013-05-13T06:48:18Z

This allows you to write portable makefiles that set GNU make-specific command line options in the environment or makefile: add them to GNUMAKEFLAGS instead of MAKEFLAGS and they will be seen by GNU make but ignored by other implementations of make.

Add new --trace[=MODE] flags, with --trace=dir

2013-05-13T05:30:24Z

This mode replaces the previous heuristic setting enabled with -O, where we would log directory enter/leave for each synchronized output. Now we only do that if --trace=dir is given.

Rename the -O "job" mode to "line" and "make" to "recurse".

Add memory allocation cleanup to loadable objects.

2013-05-04T21:38:53Z

Add gmk_alloc() and gmk_free() functions so loadable objects can access our memory model. Also provide a more extensive example in the manual.

Fix a typo in the manual.

Add support for per-job output sync.

2013-04-28T05:19:19Z

A new flag to the -O/--output-sync, "job", selects a per-job (that is, per line of a recipe) output synchronization. To support this move the close of the temp file out of the sync_output() function and don't do it until we free the child, since we may call sync_output() multiple times in a given recipe. When we set up for a new temp file, if we're in per-job mode we truncate the file and seek to the beginning to re-use it for every job.
