Subject: tests: Fix 'type defaults' error in link_cond due to main not being properly declared
X-Git-Tag: v1.16i~72

tests: Fix 'type defaults' error in link_cond due to main not being properly declared

This is related to an effort to prepare Automake for future GCC/Clang
versions which set c99 as default standard to be used.
Not properly declaring main as "int main(...)" is rejected since c99.

* t/link_cond.sh: Add (void) to main definition.
