Subject: explicitly drop Yacc, Bison < 3 compatibility in exparse.y
X-Git-Tag: 2.46.0~20^2^2~92^2~3
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6e4849d75587e21214817d03b5c27e3f391d3a7e;p=graphviz

explicitly drop Yacc, Bison < 3 compatibility in exparse.y

Yacc was already not supported as this parser is using Bison extensions, but
this at least makes explicit what our requirements are. This is the equivalent
of 4a13c9598ad3d950a251e5d3e5be8d05c59c6214. Related to #1806.
