Paul Smith	11095a90f1	Make second expansion optional (partial implementation). ... I decided this feature was too impacting to make the permanent default behavior. This set of changes makes the default behavior of make the old behavior (no second expansion). If you want second expansion, you must define the .SECONDEXPANSION: special target before the first target that needs it. This set of changes ONLY fixes explicit and static pattern rules to work like this. Implicit rules still have second expansion enabled all the time: I'll work on that next. Note that there is still a backward-incompatibility: now to get the old SysV behavior using $$@ etc. in the prerequisites list you need to set .SECONDEXPANSION: as well.	2005-10-24 13:01:39 +00:00
Paul Smith	08c8105c54	Various enhancements ... - OS/2 Patches - OpenVMS updates - Sanitize the handling of -include/sinclude with and without -k - Fix the setting of $< for order-only rules.	2004-05-16 19:16:52 +00:00
Paul Smith	a35db90275	Fix order-only prerequisites for pattern rules. (Savannah patch #2349). ... Add a regression test for this. Older libraries don't allow *alloc(0), so make sure we don't ever do that.	2004-01-07 19:36:39 +00:00
Paul Smith	6c9a393f95	Documentation and tests for order-only prerequisites. ... Add a new test suite for automatic variables.	2002-07-09 06:35:56 +00:00
Paul Smith	724925be2b	Various cleanups reported by people using the alpha release. ... Incorporate "order-only" prerequisites patch. Wrote a test for it. The test shows what might be a bug in the code; I need to look at it more closely (anyway it doesn't behave as I expected). Also I haven't done the docs yet.	2002-07-08 13:05:02 +00:00
