Subject: more precise definition of vec_new
X-Git-Tag: 2.44.1~11^2~4^2~2

more precise definition of vec_new

Unfortunately a definition/declaration with no parameters in older C is
ambiguous. Explicitly saying 'void' tells the compiler this takes no arguments.
This silences a -Wstrict-prototypes warning on GCC 8.3.

This reapplies commit 31dbec0dbb2aa17535faf9093b15b26207497056 which was backed
out due to a CI failure.
