Subject: remove unnecessary casts of allocation results in mklang.y
X-Git-Tag: 2.47.3~5^2~5
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=16954820d6c4ab7dbe6ef70d72e124b890f699cb;p=graphviz

remove unnecessary casts of allocation results in mklang.y

This input is only used to generate a C file. In C, void pointers (as are the
results of all the allocation functions) implicitly coerce to all other pointer
types.
