From: Ken Raeburn Date: Fri, 25 Jun 2004 19:42:10 +0000 (+0000) Subject: * k5-platform.h (JOIN4, JOIN4_2, JOIN3, JOIN3_2): Unused macros deleted. X-Git-Tag: krb5-1.4-beta1~271 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=84bac78452a0e1927d4ce797e3a0f24123850d14;p=krb5.git * k5-platform.h (JOIN4, JOIN4_2, JOIN3, JOIN3_2): Unused macros deleted. (JOIN__2, JOIN__2_2): Renamed from JOIN2 and JOIN2_2. Insert two underscores between the tokens supplied. All uses changed to use new macros, and not use identifiers with leading underscores. ticket: 2603 status: resolved git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@16521 dc483132-0cff-0310-8789-dd5450dbe970 --- diff --git a/src/include/ChangeLog b/src/include/ChangeLog index a0177adce..a29ede113 100644 --- a/src/include/ChangeLog +++ b/src/include/ChangeLog @@ -1,3 +1,11 @@ +2004-06-25 Ken Raeburn + + * k5-platform.h (JOIN4, JOIN4_2, JOIN3, JOIN3_2): Unused macros + deleted. + (JOIN__2, JOIN__2_2): Renamed from JOIN2 and JOIN2_2.
