Subject: Set LLONG_MAX for C89 test.
X-Git-Tag: V_9_5_P1~27
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ff3eda68ceb2e2bb8f48e3faceb96076c3e85c20;p=thirdparty%2Fopenssh-portable.git

Set LLONG_MAX for C89 test.

If we don't have LLONG_MAX, configure will figure out that it can get it
by setting -std=gnu99, at which point we won't be testing C89 any more.
To avoid this, feed it in via CFLAGS.
