Subject: templates: add __extension__ before statement expressions
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=c19e7f1fba01ab4f9a604dec3d6be14fd9fcb02a;p=deliverable%2Fbarectf.git

templates: add __extension__ before statement expressions

This removes the warnings printed by GCC with -pedantic, since
statement expressions are a GCC extension.
