Subject: build: call AC_PREREQ() first & quote argument
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=eb59d84da2b4b177d456a881222695918353a5e8;p=libevent

build: call AC_PREREQ() first & quote argument

> This macro may be used before AC_INIT.

Calling this first means establishing that the required version of
autoconf is actually available, before bothering with AC_INIT().

See:
https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.67/autoconf.html#Versioning.
