Subject: Rename %before-definitions to %start-header and %after-definitions to
X-Git-Tag: v2.3b~357
X-Git-Url: https://git.saurik.com/bison.git/commitdiff_plain/34f98f46ee16dd3719d19e002dc27b2665a2514f?hp=34f98f46ee16dd3719d19e002dc27b2665a2514f

Rename %before-definitions to %start-header and %after-definitions to
%end-header.  Don't use these declarations to separate pre-prologue
blocks from post-prologue blocks.  Add new order-independent
declarations %before-header and %after-header as alternatives to the
traditional Yacc pre-prologue and post-prologue blocks.  Discussed at
<http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
