Subject: gvpr: more tightly scope 'nextg'
X-Git-Tag: 6.0.1~16^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=11453c5fef652abfb751c6ee43b70b00b3efe6db;p=graphviz

gvpr: more tightly scope 'nextg'

This squashes a -Wclobbered compiler warning. Though, as discussed in the prior
commit, I believe this to be a false positive.

As of this commit, Graphviz builds free of -Wclobbered warnings.

Gitlab: closes #1801
