+Subject: [PATCH] timeconst.pl: Eliminate Perl warning
|
|
|
+
|
|
|
+defined(@array) is deprecated in Perl and gives off a warning.
|
|
|
+Restructure the code to remove that warning.
|
|
|
+
|
|
|
+[ hpa: it would be interesting to revert to the timeconst.bc script.
|
|
|
+ It appears that the failures reported by akpm during testing of
|
|
|
+ that script was due to a known broken version of make, not a problem
|
|
|
+ with bc. The Makefile rules could probably be restructured to avoid
|
|
|
+ the make bug, or it is probably old enough that it doesn't matter. ]
