Summary |
0001417: Need to make sure that makefiles with += and ?= are portable to all make implementations |
|
Description |
In 0000330 we added support for += and ?= but forgot to mention that there need to be a <space> character before *= and ?=.
The background is that some make implementations as an extension support the characters '+' and '?' to appear in macro names and as a result, the parser needs a leading space to properly detect += and ?=.
Note that += is supported (wihth leading space) in SunPro Make since January 1986. |
|
Desired Action |
In draft 1.1 on page 2910 after line 97964 add:
Some make implementations (e.g. SunPro Make) support the characters '+' and '?' to appear in macro names and as a result, the parser needs a leading space to properly detect += and ?=. A conforming makefile needs to have a <space> character before += or ?=. |
