Parsing large dot files produces cryptic error, request: increase YY_BUF_SIZE or give option to set it from CLI

Ubuntu 16.04. When issuing command %> got -Tpn dot_file.dot -o png_file.png I get a syntax error when the dot file is > 16KB in size. This error is with the version of Graphiz attained via apt-get. Building version stable_release_2.40.1 shows a slightly more informative message (e.g. parse error, is size > 16KB?) but offers no way to work around the issue. Building Graphviz with YY_BUF_SIZE = 2^20 resolves my issue.

Requesting that this be resolved in future releases.
