From 2a6b149c64f6ba8cc3eef70c6901ee0c67a137a7 Mon Sep 17 00:00:00 2001 From: Erik Faye-Lund Date: Thu, 6 Oct 2011 19:52:48 +0200 Subject: [PATCH] mingw: avoid using strbuf in syslog strbuf can call die, which again can call syslog from git-daemon. Endless recursion is no fun; fix it by hand-rolling the logic. As a side-effect malloc/realloc errors are changed into non-fatal warnings; this is probably an improvement anyway.
