From: Ken Raeburn Date: Thu, 3 Mar 2005 23:25:32 +0000 (+0000) Subject: time-delta parser doesn't work on HP-UX 10 X-Git-Tag: ms-bug-test-20060525~328 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=3e65c52eb55e0568749c698a312619a3001ceeab;p=krb5.git time-delta parser doesn't work on HP-UX 10 A build on Lenny's machine (built with gcc 2.7, thread support disabled, static libraries only) is failing tests because the HP header files define "WS" as a macro that expands to 2, while the delta-t grammar uses "WS" as the name of a terminal symbol (which under bison turns into a C macro). Renaming the terminal in the grammar (and custom lexer) fixes the problem. * x-deltat.y (tok_WS): Renamed terminal from "WS", which conflicts with HP-UX 10 header files. Updated all productions. (mylex): Updated. * Makefile.in ($(srcdir)/deltat.c): Enable dependencies in maintainer mode. * deltat.c: Updated. ticket: new target_version: 1.4.1 git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@17110 dc483132-0cff-0310-8789-dd5450dbe970 --- diff --git a/src/lib/krb5/krb/ChangeLog b/src/lib/krb5/krb/ChangeLog index cc0d58cd3..8a60cabac 100644 --- a/src/lib/krb5/krb/ChangeLog +++ b/src/lib/krb5/krb/ChangeLog @@ -1,3 +1,12 @@ +2005-03-03 Ken Raeburn + + * x-deltat.y (tok_WS): Renamed terminal from "WS", which conflicts + with HP-UX 10 header files.
